Three experiments were conducted to investigate the interaction between micronization and cultivar of wheat on grain chemical composition and feeding value for chickens. Micronized whole grain feeding was evaluated in one experiment using inclusion levels of 10 and 50% for starter and grower diets, respectively. Dietary enzyme was used in two other experiments to study its interaction with micronization and genotype of wheat. Wheat cultivars Genesis, Kyle, and Katepwa were micronized at 100°C for 50 s and incorporated into broiler diets. Micronization improved overall feed efficiency, but did not always increase body weight. When feeding whole grain to birds, micronization improved feed efficiency from 21 to 42 d and 0 to 42 d, but did not affect final body weight. Micronization of wheat cultivars reduced early growth rate of all birds, regardless of wheat form in the diets. Micronization did not impact AME and digesta viscosity. Cultivar Kyle had a higher dietary AME and a lower digesta viscosity, and resulted in feed efficiency and weight gain values superior to those of either Genesis or Katepwa (exps. 2 and 3). Enzyme increased weight gain, feed efficiency and dietary AME, and decreased digesta viscosity. Key words: wheat, cultivars, micronization, AME, broilers

Feeding Value

Field, feeding, and digestion experiments were conducted from 1966 to 1968 to determine the overall feeding value of corn (Zea mays L.) silages grown in an area where well-eared corn is not assured because of climatic conditions. The nutritive value of the silages was determined in 112-day feeding experiments with a total of 192 steer calves averaging 191 kg body weight. The variables in the 25 factorial experiment were early-maturing Pride 5 cultivar versus late-maturing Warwick 600, harvested on either September 6 or 26, fed with 0 or 1.5 kg concentrate/100 kg body weight daily, to Hereford or Angus steers penned in groups or fed individually. Mean green yields and crude protein and fiber contents were higher, and ear dry-matter (DM) yields, and DM and nitrogen-free extract contents were lower for Warwick 600 than those for corresponding Pride 5 silages. Differences in silage and total ration DM intakes, steer gains, and feed efficiency between cultivars and harvest dates were not statistically significant. Supplementation reduced silage DM intake (P < 0.01), and increased total ration DM intake (P < 0.01), body weight gain (P < 0.01), and feed efficiency (P < 0.01). DM intake was greater (P < 0.01) and gains slightly higher for Angus than for Hereford steers. DM, protein, and fiber digestion coefficients were greater for early-cut and less for late-cut Pride 5 than for corresponding Warwick 600 silages. Silages ranked Warwick 600 late-cut, Pride 5 late-cut, Pride 5 early-cut, and Warwick 600 early-cut, based on the calculated body weight gain per hectare of silage.

Abstract The aim of the study was to evaluate prediction methods, validation approaches and pseudo-phenotypes for the prediction of the genomic breeding values of feed efficiency related traits in Nellore cattle. It used the phenotypic and genotypic information of 4,329 and 3,594 animals, respectively, which were tested for residual feed intake (RFI), dry matter intake (DMI), feed efficiency (FE), feed conversion ratio (FCR), residual body weight gain (RG), and residual intake and body weight gain (RIG). Six prediction methods were used: ssGBLUP, BayesA, BayesB, BayesCπ, BLASSO, and BayesR. Three validation approaches were used: 1) random: where the data was randomly divided into ten subsets and the validation was done in each subset at a time; 2) age: the division into the training (2010 to 2016) and validation population (2017) were based on the year of birth; 3) genetic breeding value (EBV) accuracy: the data was split in the training population being animals with accuracy above 0.45; and validation population those below 0.45. We checked the accuracy and bias of genomic value (GEBV). The results showed that the GEBV accuracy was the highest when the prediction is obtained with ssGBLUP (0.05 to 0.31) (Figure 1). The low heritability obtained, mainly for FE (0.07 ± 0.03) and FCR (0.09 ± 0.03), limited the GEBVs accuracy, which ranged from low to moderate. The regression coefficient estimates were close to 1, and similar between the prediction methods, validation approaches, and pseudo-phenotypes. The cross-validation presented the most accurate predictions ranging from 0.07 to 0.037. The prediction accuracy was higher for phenotype adjusted for fixed effects than for EBV and EBV deregressed (30.0 and 34.3%, respectively). Genomic prediction can provide a reliable estimate of genomic breeding values for RFI, DMI, RG and RGI, as to even say that those traits may have higher genetic gain than FE and FCR.

An experiment was carried out to determine the growth performance and haematological indices of Red Sokoto goats placed on oil palm leaf meal (OPLM)-wheat offal based diet. Six goats aged 12-18 months, weighing 15 – 20kg were randomly assigned to three treatments, comprising two animals each in a Completely Randomized Design. Each animal received 1kg of the diet daily for 56 days and weighed weekly. Results showed that final body weight was significant (P<0.05) with goats on T3 having the highest (21.50kg). The feed intake, body weight gain and Feed Conversion Ratio (FCR) were significantly different (P<0.05). T3 had the highest feed intake (305.35g/d), highest body weight gain (90.84g/d) and the best FCR (3.36). Significant differences (P <0.05) were observed in the Red Blood Cell (RBC), Packed Cell Volume (PCV) and Haemoglobin (Hb) counts, ranging between 3.12 - 4.20x106ml; 23.00 -30.50% and 7.70 - 10.15g/dl respectively with goats on T3 having the highest.  The inclusion of OPLM enhanced body weight gain, FCR, RBC, PCV, and Hb counts of the goats. Therefore the oil palm leaf meal diets are recommended for better goat production. Key word: Growth performance; Oil Palm Leaf meal., Blood profile., Creatinine., Red Sokoto Goat.

Three groundnut meals namely: groundnut cake (GNC), locally processed groundnut cake (kulikuli) and toasted groundnut seed(kernel) meal (TGSM) were incorporated in rabbit diets at two levels to generate six diets: 18% GNC, 22% GNC, 18% Kulikuli, 22% Kulikuli, 18% TGSM and 22% TGSM respectively, and 18% GNC also served as the control diet. Twenty four (24) six weeks-old growing rabbits of mixed breeds and sexes with mean initial weight of 568.75±l2.85g were randomly allocated to the six dietary treatment groups, such that each had four rabbits and each rabbit formed a replicate in a completely randomized design laid out in a 2X3 factorial arrangement and fed ad libitum, for 70 days. The main effects showed that while the treatment groups fed TGSM were significantly depressed (p<0.05). rabbits fed GNC and kulikuli were not significantly different (p>0.05) for average daily feed intake, daily body weight gain and final body weight. Feed conversion ratio (FCR) was not significantly (p >0.05) affected among treatment groups. Rabbits fed TGSM had significantly (p<0.05) better apparent digestibility coefficient (78.04%) than those on kulikuli (75.81%6) and the group on kulikuli were better than animals fed GNC (72.09%) for fat digestibility. Fibre digestibility was also significantly different (p <0.05), with rabbits fed kulikuli having the poorest fibre digestion (15.63 %). Crude protein, dry matter and NFE apparent digestibility coefficients were not significantly (p >0.05) affected. Among all the parameters measured, only fat and fibre digestibility coefficients had significant (p <0.05) interactions and NFE digestibility was significantly affected (p <0.05) by level of inclusion, with groups fed 22% digesting it better. Feed cost kg gain did not differ significantly (p >0.05) among the treatment groups. Growth was still on the rise and there was a significantly (P<0.01) strong relationship (correlation and regression) between feed intake and weight gain for all the treatment groups. was concluded that both kulikuli and TGSM are potential feed resources for rabbits, more available to house hold farmers, equally economical as GNC and better still if groundnut farmers and or processors of kulikuli raise rabbits, though TGSM had less value for growth rate compared to GNC and Kulikuli at these levels of inclusion

One hundred and twenty (120) 16 weeks old White Leghorn layer breeds were used for the study. The objective of the study was to determine effect of photoperiod on layer chicken. The research was carried out at the Poultry Section of the Animal farm of the Department of Animal Science Education, Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development, Mampong. Four treatments made up of 12 hours of light, 14 hours of light, 16 hours of light and 18 hours of light were used for the study. Each treatment was replicated three times with 10 birds per replicate in a Completely Randomized Design. Birds were exposed equally to common daylight and in the evenings, lights were turned on at specified periods. Growth parameters measured were initial body weight, daily feed intake, daily weight gain and final body weight. Egg traits measured were egg weight, albumen height, yolk color and yolk weight. The data collected were analyzed using General Linear Model procedure of Statistical Analysis System. Results from the study indicated that, varied photoperiod regimes had no significant (P>0.05) effect on initial body weight, daily feed intake but had significant (P<0.05) effect on daily weight gain and final body weight of growth traits. Photoperiod had no significant (P>0.05) effect on the egg characteristics of the white Leghorn layer bird. It was concluded from the study that, increasing photoperiod had no positive effect on growth and egg characteristics of the white Leghorn layer.

Abstract Feed cost is the major input cost in the mink industry and thus improvement of feed efficiency through selection for high feed efficient mink is necessary for the mink farmers. The objective of this study was to estimate the heritability, phenotypic and genetic correlations for different feed efficiency measures, including final body weight (FBW), daily feed intake (DFI), average daily gain (ADG), feed conversion ratio (FCR) and residual feed intake (RFI). For this purpose, 1,088 American mink from the Canadian Center for Fur Animal Research at Dalhousie Faculty of Agriculture were recorded for daily feed intake and body weight from August 1 to November 14 in 2018 and 2019. The univariate models were used to test the significance of sex, birth year and color as fixed effects, and dam as a random effect. Genetic parameters were estimated via bivariate models using ASReml-R version 4. Estimates of heritabilities (±SE) were 0.41±0.10, 0.37±0.11, 0.33±0.14, 0.24±0.09 and 0.22±0.09 for FBW, DFI, ADG, FCR and RFI, respectively. The genetic correlation (±SE) was moderate to high between FCR and RFI (0.68±0.15) and between FCR and ADG (-0.86±0.06). In addition, RFI had low non-significant (P &gt; 0.05) genetic correlations with ADG (0.04 ± 0.26) and BW (0.16 ± 0.24) but significant (P &lt; 0.05) high genetic correlation with DFI (0.74 ± 0.11) indicating that selection for lower RFI will reduce feed intake without adverse effects on the animal size and growth rate. The results suggested that RFI can be implemented in genetic/genomic selection programs to reduce feed intake in the mink production system.

QUAIL (Coturnix-Coturnix Japonica) GROWER PERFORMANCE SUPPLIED WITH MANURE FLOUR DEGRADED BY BLACK FLY LARVAE (H.ILLUCENS L.) TO REPLACE FISH MEAL. This study aims to determine the manure yield of black fly larvae replacing fish meal in the quail feed of the grower phase. The materials used in this study were 100 unsexed quails, 3 weeks old; the dimension of cage was 40 x 40 x 20 cm. The quails were arranged randomly in each unit. The study was realized by using a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments were R0 = 0% degraded manure flour (MHD); R1 = 4% MHD flour; R2 = 8% MHD flour; R3 = 12% MHD flour. The research variables consisted of ration consumption, body weight gain and feed efficiency. The results obtained showed that treatments provide a very significant influence (P <0.01) on ration consumption. Body weight gain and feed efficiency were not significant different (P> 0.05). The conclusion of this study is that MHD flour up to the 12% level can be used in quail rations replacing fish meal. Keywords: Quail, MHD, Fish meal.

This study aimed to assess the effect of quantitative dietary restriction during refeeding on the performance, body chemical composition, and deposition, weight gain of organs and carcass parts of quails reared for meat (Coturnix coturnix coturnix). A total of 144 quails, between 11 to 42 days old, were distributed in a completely randomized design, 4x2 factorial scheme, at four levels of feed restriction (ad libitum, 30%, 50% and 70% restrictions on the daily intake ad libitum) for both genders. Therefore, there was eight treatments with three replicates and six birds each. At the tenth day of age, the animals were housed in cages, where remained for four days under adaptation. Dietary restriction was applied between the days 15 and 35 while refeeding was carried out from day 36 to 42. Compensatory weight gain (CWG), i.e. weight gain of organs and carcass parts, and feed efficiency (FE) were improved for quails under feed restriction. Fat (F), crude protein (CP), protein deposition rate (PDR) and fat in females (FDf) and carcass retained energy in females (CREf) increased linearly as restriction levels decreased. Maximum estimates of feed intake for males (MFIm), compensatory weight gain for males (CWGm) and females (CWGf), feed efficiency for males (FEm), protein deposition for males (PDm) and carcass retained energy in males (CREm) were obtained with restriction levels of 43.56%, 30.56%, 63.93%, 62.63%, 80.25%, 1.94% and 09.34% if compared to ad libitum, respectively. As a result, we concluded that according to quantitative feed restriction level, significant increases in feed efficiency and body weight gain, as well as decreases in carcass fat throughout quail refeeding period. As for gender, given the existing sexual dimorphism, females lost greater body weight than males under dietary restriction, besides showing higher protein and fat gains in the carcass and an enhanced feed efficiency during refeeding.

The efficacy of tulsi (Ocimum sactum) and neem (Azadirachta indica) leaves extract as a growth promoter were studied in broiler. A total of 40 day-old broiler chicks were purchased from Kazi hatchery and after three days of acclimatization the chicks were randomly divided into four groups (n=10). No vaccination schedule was practiced and no antibiotic was added in ration of group A, B, C, and D respectively. Group A served control without any supplements while group B, C and D were supplemented with combination of tulsi and neem extract @ 1 ml, 2ml and 3 ml/liter of drinking water. Live body weight gain was recorded weekly up to 6th weeks and hematological studies were performed at 21st and 42nd day of experiments. At the end of 42nd day of experiment final body weight of group A, B, C and D were 1561± 12.10 g, 1698± 12.87 g, 1608± 12.04 g and 1763± 13.28 g, respectively. The birds of group D utilized their feed more efficiently among the treatment groups (p<0.05). The net body weight gain were, 1533± 11.98 g, 1443± 11.32 g and 1588± 12.10 g in treated groups compared to control group (1393± 11.07 g ) and total net profit per broiler was 19.08, 40.10, 20.68 and 45.07 Taka , respectively. Hematological parameterss (TEC, PCV, Hb and ESR) were not significantly changed among the treated and control group suggesting no side effects of herbal extracts in broiler. It can be concluded that tulsi and neem extract is economic and safe in broiler production.DOI: http://dx.doi.org/10.3329/bjvm.v11i1.17728 Bangl. J. Vet. Med. (2013). 11 (1): 1- 5
