Abstract

Variance components for additive direct, additive maternal, permanent environmental maternal effects, the covariance between additive direct and maternal effects were estimated by restricted maximum likelihood, fitting four animal models from 1359 pedigree male birth weight records of Afrikaner cattle of Zimbabwe. All investigated models included a random direct genetic effect, but different combinations of random maternal genetic and permanent environmental effects as well as direct-maternal genetic covariance. The direct heritability (h2a) ranged from 0.40 to 0.43 when the maternal genetic effects were included in the model, whereas h2a was highest 0.45 when maternal effects were excluded. The maternal heritability (h2m) was 0.00 when only maternal genetic effects were included in the model and were 0.09 and 0.09 when the permanent environmental effect of the dam was added. The permanent environmental effect of the dam was negligible. A weak negative covariances between direct and maternal genetic effects (σ2am ) was observed in model which had all the random effects fitted and proved to the appropriate among the four models using the log likelihood ration test.

Abstract

Fishmeal is one and possibly the major conventional source of protein in poultry feeds in Nigeria. At present the astronomical rise in the prices of this and other conventional ingredients has put enormous pressure on the poultry farmers to look for alternatives. The effect of poultry hatchery waste meal on the replacement of fish meal on equal protein basis of 0,25, 50, 75 and 100% in the diets of 100 Isa brown pullet groves and layers on their performance characteristics and egg characteristics during 14 to 20 weeks was investigated. Five dietary treatments were randomly applied to 10 groups of 10 birds each. Observations were made at four weeks is nitrogenous with 2600kcal/kg/ME and 15% crude protein respectively. It was observed that replacement of fishmeal (FM) and poultry hatchery waste meal (PHWM) did not produce significant (p>0.05) effect on the performance characteristics. Significant differences (p<0.05) was obtained for birds on treatments 1, II and III to that of birds on treatments IV and V during 5th periods. There were also significant difference (p<0.05) between treatments during the 4th and 5th periods. Poorer values were obtained for food than the values obtained during the 1st period. Mean daily egg yield also show a significant difference (p<0.05) in the egg yield produced by birds on diets I and V for the 5th periods. Egg quality characteristics show a similarity (p>0.05) during 3rd, 4th and 5th period except for eggs length and egg volume showing significant differences (p<0.05) between diets I and IV. It is therefore recommended that PHWM could replace FM completely in layers diet without any adverse effect on the performance characteristics.

Abstract

The study was conducted to determine the haematological and biochemical indices and the naturally occurring haemo and gastrointestinal microbes of 150 matured street pigeons in Owerri, Imo State, Nigeria. The PCV, WBC, MCV, MCH and total bilirubin values of the female pigeons were significantly (p<0.05) different from the male counterpart. All the other haematological and serum biochemical parameters measured were similar (p>0.05) between the two group. Out of 150 street pigeons examined for prevalence of parasites, 70 (46.70%) of them were infected with gastro-intestinal parasites of which 30 (42.93%) were males and 40 (57.1%) were females. Four gastro-intestinal parasites were identified with Trichomonas sp. giving the highest prevalence rate (42%), followed by Eimeria sp. (28%), and whereas Coccidia sp. and Ascaridia sp. returned the least with each having the prevalence rate of (14%). Results of haemo -parasitological examination of thin blood smears revealed haematozoa of two genera: Haemoproteus sp. which was more common gave a prevalence rate of 40 (66%) for the male and 70 (87%) for the female pigeons. Plasmodium sp. with prevalence of 20 (33%) and 10 (12%) in male and female pigeons respectively. Fecal cultures recorded high growth of bacterial organisms, of which Proteus sp. returned 50 (83%) and Enterococcus sp. returned 10 (16%). In totality, 40% of the pigeons had bacterial infections. In conclusion, the prevalence of gastrointestinal and haemoparasites in street pigeons in Owerri, Imo State, Nigeria. However, these parasites did not cause any visible deleterious effects in the blood parameters of the pigeons examined.

Abstract

This work was conducted on Japanese quails (Coturnix japonica) to determine the effects of sex, colour and weight group on their carcass characteristics. The birds were housed in deep litter pen at the poultry unit of University of Maiduguri Teaching and Research Farm and fed with broiler starter marsh from 5-8 weeks then later on from 8-52 weeks layer mash were introduced. The birds were divided into various groups (based on sex, colour and weight groups). The experiment lasted for 52 weeks in which the birds were slaughtered and divided into various parts and weighed. Results obtained were subjected to statistical analysis using Analysis of Variance (SPSS 16.0 statistical package) and the means were separated using Duncan Multiple Range Test. Effect of sex on carcass characteristics were significant (p<0.05) with female having higher mean value than the male for live weight and bled weight respectively. Also, there were significant effect (p<0.05) of color type and weight group on carcass traits. Results obtained form this research work will serve as a basis for selection of desirable traits in Japanese quail and may contribute to the body of knowledge with regards to this animal species.

Abstract

For this study, 15 young male rabbits of same breeds, with age range of 11-12 weeks old and weighing 1.0 ±0.2kg were used. These were randomly assigned to three treatments, each consisting of five rabbits per treatment. The treated groups(Treatments B and C) and the control group (Treatment A)were injected intramuscularly with charcoal-extracted bovine follicular fluid (FF), charcoal extracted bovine testicular fluid (TF) and charcoal treated distilled water (DW) respectively, at the rate of 0.2ml per rabbit on every other day and on three different occasions. Duration of the treatment lasted six days. Data were analyzed using descriptive statistics and ANOVA. After administration of the different treatments, body weight (BW), testes weight (TW) and histometric studies (HS) were conducted. Histometric studies included: seminiferous tubule diameter (STD), cellular elements (CE), stages of the cycle of seminiferous epithelium (CSE), determination of daily sperm production (DSP) and daily sperm production per gram testis (DSP/g). Figures obtained pertaining to their weights showed that they grew significantly over their initial weights with animals treated with TF showing highly significant (p<0.01) weight increase of 0.78kg, which on the average represents 110.8% and 95% higher in weight gain than those of FF and control groups. There were no significant differences (p>0.05) in paired TW among the three different groups. STD of control group was significantly (p<0.01) higher (203.46µ) than those of the treated groups. There were no significant (p>0.05) differences among the three different treatments in the frequency occurrence of stages 2 and 7 of the CSE, DSP and DSP/g testes. However, the frequency of occurrence of stages 1, 4 and 8 of the CSE differ significantly (p<0.01) between control group and treated groups. There was a highly significant spermatozoa decrease (p<0.01) in the treated groups when compared with control group and this supports the ability of the inhibin from bovine follicular and testicular fluids to inhibit the onset of active spermatogenesis.

Abstract

Fifteen days prior to weaning, sixteen West African dwarf (WAD) ewes (Initial BW 19.13±1.53kg) on a basal diet of Panicum maximum were allotted into 4 treatment groups A, B, C and D of 4 replicates each. The mexican sunflower leaf (MSL) replaced wheat bran (WB) gravimetrically at 0, 15, 30 and 45%. Treatment A served as control. The experiment lasted for one week. Digestibility was determined using a 6-d total fecal collection. The 16 ewes were previously lambed 10 weeks before the commencement of this study and tagged to their respective treatments. Parameters measured were nitrogen intake, nitrogen balance, nitrogen apparent digestibility and nitrogen retention. Data were analyzed using descriptive statistics and ANOVA. Animals on treatment B had the highest N-intake (18.1g/d), N faecal (1.7 g/d), N absorbed (16.4 g/d) and N balance (16.3 g/d) and this was significant (P<0.05). Urinary nitrogen g/d was significantly higher (P<0.05) with increasing inclusion of MSLM in the ration while protein retention increased from treatment A (0% MSLM) to treatment B (15% MSLM) (89.8 – 90.3%) and subsequently decreased from treatment B (15%MSLM) to D (45% MSLM) (90.3 - 84.4%). Nitrogen balance was positively related to DM intake and N intake. The overall regression were nitrogen balance (NB) =2.50+0.067 DMI; R2 = 0.9372, (P=0.3937) and NB= 0.75+0.9066 NI; R2 = 0.9957, (P=0.1401). Inclusion of up to 30% MSLM in the diets of lactating ewe appeared most beneficial to sheep as it had no negative effects on nitrogen intake.

Abstract

This study was carried out on Japanese quails (Coturnix japonica) to determine the effect of sex, colour and weight group on various organ weights. The birds were housed in deep litter pen at the poultry unit of University of Maiduguri Teaching and Research Farm. Birds were fed with broiler starter marsh from 5-8 weeks then, layer mash from 8-52 weeks. The birds were divided into various groups (sex, colour and weight groups). The experiment lasted for 52 weeks. Birds were slaughtered and eviscerated. The organs were weighed using sensitive scale and the results obtained were subjected to statistical analysis using Analysis of Variance (SPSS 16.0 statistical package) and the means were separated using Duncan Multiple Range Test. Effect of color on organ weight were statistically not significant (p>0.05) except for fat weight, while the effect of sex on organ weight indicated that male and female differed significantly (p<0.05) for all organ weights except liver weight. Similarly, weight group had significant effect (p<0.05) on all the carcass traits except liver and testicular weight. The information obtaained in this study could serve as an immense advantage to farmers in the selection of desirable traits in Japanese quail. This will also enhance the farmers to maximise their profits.

Abstract

A study was conducted to investigate the influence of breed and age on carcass composition of Nigerian goats. Mean values of lean, bone, fat and lean: Bone ratios were 64.64, 31.95, 3.42 % and 2.05, respectively. Sokoto Red goats had more lean, less bone and higher lean: bone ratio than Sahel goats (P<0.05). Mature goats had significantly less bone and higher lean: bone ratio. There was significant breed x age interaction in carcass lean, carcass, bone and lean: bone ratio, such that the superiority of Sokoto Red in percent lean and lean: bone ratio and the higher percent bone of the Sahel hold true only among mature goats. Carcass fat was not influenced by breed or age of goats.

Abstract

Polymerase chain reaction diagnosis of Candidatus liberibacter asiatic associated with citrus Huanglonbing disease is molecular technique which is used for detection of disease when pathogen present is very low concentration in disease sample. Among these three DNA isolation methods viz., commercial kit method, sodium sulphite method and membrane bard nucleic acid technique, sodium sulphite method is cost effective for commercial use. In nucleic acid membrane method for DNA extraction isolation there is no use of liquid nitrogen. Polymerase chain reaction detection of disease is based on principal of thermal cycling in which PCR instrument allow to run generally 60-65 thermal cycle, during PCR operation it allow different stages of cycle at different temperatures for different period of time i.e. initiation (940C), denaturation (940C), primer annealing (600C), extension/elongation step (720C), final elongation (720C) and holding temperature (40C). PCR based diagnosis system is developed for detection of greening bacteria. The comparative cost of detection by various combinations of reagent and sampling time was determined and cost effective technology was standardized and validated.

Abstract

A naturally dead stray dog suffering from perianal gland adenoma was reported here. On post-mortem examination 5 cm large ulcerated mass was found at the base of tail partially obstructing anal opening. Histologically the tumour comprised of large round neoplastic cells with round centrally located nuclei, eosinophilic cytoplasm and well distinct cell borders which were surrounded by single layered hyperchromatic reserve cells. The neoplastic mass showed encapsulation by fibrous tissue and trabeculae in between. The mass was supposed to be affecting normal defecation process leading to constipation and subsequent toxaemia leading to death of the dog.

Abstract

A retrospective study to determine the pattern of isolation of mastitis causing organisms from milk samples of cattle, sheep and goats submitted to the Microbiology laboratory of the Department of Veterinary Pathology and Microbiology Ahmadu Bello University Zaria from 1980-1991 and 1999-2009 was conducted. The samples were subjected to cultural isolation and biochemical characterization. The results of the isolates were assembled, reviewed and summarised. A total of 227 milk samples were submitted from cattle (40), sheep (31) and goats (156) respectively, from the years 1980 to 1991 and 1999 to 2009 and subjected to cultural isolation and biochemical characterization. A total of 18 different organisms were isolated from 158 of the samples submitted. Six of the submitted samples were un-typeable while 63 were culture negative i.e showed no growth. The most commonly isolated mastitis causing organisms from all samples were: Staphylococcus aureus (26.51%), Escherichia coli (12.20%), Staphylococcus spp (10.24%), Streptococcus spp (6.63%) and Corynebacterium spp (7.32%). Other organisms are, Micrococcus (1.22%), α-hemolytic Streptococcus (1.83%), β- haemolytic Streptococcus (2.42%), Pseudomonas aeroginosa (4.88%), Enterobacter spp (1.83%), Proteus spp (4.89%), Lactobacillus spp (2.42%), Pasteurella spp (4.27%), Klebsiella spp (3.05%), Citrobacter spp (0.61%), Candida albican (0.61%), Flavobacterium spp (0.61%), Bacillus spp (3.67%), Acinetobacter spp (1.20%) and Sarcina spp (0.61%). Staphylococcus aureus was the most predominant organism isolated from cattle, sheep and goat milk. There was a significant reduction in occurrence of mastitis from 201 (88.55%) cases within 1980-1991 and 26 (11.45%) cases within 1999-2009.

Abstract

A study was conducted to assess the effects of less-saturated fats [Egg yolk (EY) and soya oil (SO)] on characteristics and acceptability of beef sausages. Each of the fats was incorporated in beef sausages at three levels (5%, 10% and 15%), and compared with products formulated with only lean beef (Control). Fresh boneless beef was obtained and thoroughly trimmed of excess visible fats, and then minced. The minced beef was divided into portions of 4kg, and were randomly assigned to the fats. The fats were then mixed with the minced meats and allowed 15 minutes for the meat to absorb the fat. The products were formulated and evaluated for their sensory characteristics using BSI (1993) method, and storability by laboratory analyses. Addition of both fats up to 15% improved (P<0.001) tenderness and juiciness of the products. Increasing levels of EY caused a weakening of the product’s flavour intensity, had no effect (P>0.05) on flavour liking and reduced acceptability of the EY3 products. Increasing levels of SO improved (P<0.001) flavour intensity, flavour liking and overall acceptability of the products. Both fats increased the unsaturated fatty acid contents of the products but had no significant (P>0.05) effect on product storability. Comparatively, inclusion of SO up to 15% in beef sausages was preferred (P<0.001) to that of EY. SO could be used up to 15% in beef sausages for improved sensory characteristics and acceptability.

Abstract

This study was conducted to find alternative binders to substitute for polyphosphate in frankfurter-type sausages. Fresh albumen (FA) at 32.5 (FA1), 49 (FA2) and 65 (FA3) g/kg meat (equivalent to 5, 7.5 and 10g dry matter/kg meat), and dried albumen (DA) at 5 (DA1), 7.5 (DA2) and 10 (DA3) g/kg meat were used to formulate the products, and compared with those formulated with polyphosphate (5g/kg meat) as binder. The Completely Randomized Design was used, and products were formulated in triplicates. They were vacuum-packed in transparent packaging bags and stored at 2°C for sensory and laboratory analyses. From the results, egg albumen had no significant (P>0.05) effects on the cooking losses of the FA1, FA2, DA1 and DA2 products, but the losses in these products were significantly (P<0.01) lower than in the DA3 and FA3 products. The FA1 and FA2 products were juicier than the FA3, control, DA2 and DA3 products. The acceptability of the products was however, not significantly (P>0.05) different. The egg albumen however, increased the crude protein and reduced fat contents of the DA and FA products. It was cheaper acquiring egg albumen for the FA1 products than acquiring polyphosphates, but it’s more expensive acquiring dried albumen for the DA products, although the products had acceptable yield and sensory characteristics.

Abstract

After a previous 84-d performance phase on growing WAD ewe, Studies was conducted using sixteen West African dwarf (WAD) ewe-lambs weighing between 17.50 and 17.88kg on a basal diet of Panicum maximum were allotted into 4 treatment groups A, B, C and D of 4 replicates each. The MSL replaced Wheat bran (WB) gravimetrically at 0, 15, 30 and 45%. Treatment A served as control. The experiment lasted for one week. Digestibility was determined using a 6-d total fecal collection. Ewes were given ad libitum access to feed and water. Parameters measured were voluntary dry matter intake (VDMI), which comprised concentrate dry matter intake (CDMI) and grass dry matter intake (GDMI), Apparent Digestibility Coefficients of DM, CP, NDF, ADF, ADL, Organic matter (OM) and Energy . Data were analyzed using descriptive statistics and ANOVA .The VDMI (g/d) varied from 392.30 - 695.00, CDMI (g/d) varied from 181.80 - 536.80 and GDMI (g/d) varied from 130.65 - 215.95 for ewe-lambs. Apparent Digestibility Coefficients of NDF, ADF, ADL, organic matter (OM) and Energy were similar. Approximately 75.5 ±1.1% of the VDMI came from the supplement. Diets containing 15% MSLM was superior to others for CDMI (181.80 – 536.80 g/day), CP intake (17.72 – 32.40 g/day/kgW0.75), Digestible DMI (49.45 - 80.68 g/day/kgW0.75) and Digestible CPI (13.68 - 27.16 g/day/kgW0.75) while GDMI (130.65 – 215.95 g/day) for diets containing 30% and 45% MSLM were significant (p < 0.05). Inclusion of up to 45% Mexican Sunflower Leaf in the diets of growing ewe to replace Wheat bran was adequate.
