The objective of the study was to ascertain the feed intake, acceptability of hay and weight gain by yankasa rams fed basal diets of either natural grass hay (NGH) as control, Digitaria exilis hay (DEH), Bracharia decumbens hay (BDH) or Digitaria decumbens hay (DDH) along with equal amounts of concentrate feed as supplement. The 10-week experiment was conducted at the College farm of the National Veterinary Research Institute (NVRI), Vom, Plateau State, Nigeria using Completely Randomized Design. The four hays were allotted randomly to twenty rams housed in separate pens. There were five rams per treatment. Each animal was served 2 kg of the hay treatment, plus 200 g concentrate supplement. The parameters measured were feed intake (FI), water consumed (WC), hay acceptability (HA), weekly weight (WW), total weight gained (TWG) and daily weight gain (DWG) by rams. Hay treatment affected weekly weight of yankasa rams significantly. Daily weight gain was 142.9, 60.7, 42.9 and 10.7 g per day for rams fed with BDH, DDH, DEH and NRH, respectively. At week 10, rams fed with BDH were significantly heavier by 78.0 % than rams fed NGH and heavier by 33.2 % on aggregate than rams fed with DEH and DDH. Total weight gain of rams fed BDH was 809.1 % higher than TWG of animals fed with the control (NGH) treatment. Yankasa rams consumed 2.5 litres of water per head daily. The rams consumed significantly more of the natural grass hay (NGH) than the other hays. Acceptability of NGH, DEH and BDH was similar but DDH was not well accepted by rams. The great prospects of Bracharia decumbens hay for fattening yankasa rams, warrants expansion of this grass by NVRI.

Increasing concern about some animal production systems has placed considerable value on humanitarian breeding systems, aimed at ensuring animal welfare and comfort. Raising calves is one of the most important stages in a milk production system. This study aimed to evaluate and compare the performance of Holstein dairy calves raised by two farming systems: conventional individual (CI) and collective with automatic calf feeder (CACF). Fourteen, 15-day-old Holstein dairy calves having an average initial body weight of 40 kg, were used. The animals were distributed in a completely randomized design with seven animals per treatment. The variables evaluated were the milk and feed intake, body weight, hip height, thoracic circumference and daily weight gain. The average milk intake was lower in the CACF (3.5 L animal-1 day-1) than CI (5.1 L animal-1 day-1) system. However, the feed intake was higher in the CACF (1.205 kg animal-1 day-1) compared to CI (0.910 kg animal-1 day-1) system. Body weight, thoracic circumference, hip height and daily weight gain were similar between the two systems. The CACF raised calves had a higher concentrate intake and lower milk intake than the calves raised under the CI system.

Phytase is essential for enhancing nutritional value of feed and improving animal growthperformance and health. A study was conducted to evaluate the influence of Smartchoicephytase enzyme supplementation in the diet of starter broiler chickens. A total of 150 Rossstrain broiler chicks were used for the study and allotted to five treatment groups of 30 birdseach. Each group was further divided into three replicates of 10 birds per replicate. Five isonitrogenous(21.40% CP) and iso-caloric (2975.40 kcal/kg ME) dietary treatments werecompounded to contain 0g/100kg (T ), 10g/100kg (T ), 15g/100kg (T ), 20g/100kg (T ) and 1 2 3 425g/100kg (T ) of a commercial Smartchoice phytase enzyme preparation for 28 days in a 5Completely Randomized Design (CRD). Feed and water were provided to the chicks adlibitum.Daily feed intake and weekly body weight were measured. The result showed that thedaily feed intake and daily protein intake were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation. Final live weight, daily weight gain and total weight gain weresignificantly different among treatments. Protein efficiency ratio were significantly (P<0.05)higher in T (2.10) than T (1.80) but similar to T (2.05), T (2.05) and T (1.96). Feed 1 5 2 3 4conversion ratio was significantly (P<0.05) different in T5 (2.58) and T (2.02) but similar 1(P>0.05) in T (2.02), T (2.28), T (2.31) and T (2.38). Mortality was lowest in T5. Total feed 1 2 3 4cost per bird and daily feed cost per bird were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation while cost per kg of feed and daily feed cost per bird were notsignificantly (P>0.05) affected. The findings from this study showed that Smartchoicephytase enzyme could be supplemented up to 20g per 100kg in the diet of starter broilerchickens.

This study was carried out to investigate the performance of broilers fed graded levels of Dry Distilled Cassava with Soluble (DDCS). In a 28-day trial, one hundred and forty-four (144), 5-week old, un-sexed Arbor acre strain broiler chicks (average weight of 1.09±0.02 kg) were randomly allocated to four dietary treatments of wheat offal (WO) and DDCS (12% WO + 0% DDCS = 0% DDCS; 8% WO + 4% DDCS = 4% DDCS; 4% WO + 8% DDCS = 8% DDCS and 0% WO + 12% DDCS = 12% DDCS) in completely randomized design. Each treatment had 2 replicates of 18 birds each. Dry matter feed intake (FI g/day), daily weight gain (g/day) and total weight gain (kg) decreases with increase in the levels of DDCS, while the feed conversion ratio (FCR) increases with increase in levels of DDCS, respectively. However, there was no significant (P>0.05) differences in the carcass evaluation measured. It was concluded that DDCS could replace wheat offal in the diets of broilers up to 8% without significant difference in growth and feed intake without detrimental effects on carcass quality of the birds.     Cette étude a été réalisée pour étudier la performance des poulets de chair nourris à des niveaux échelonnés de manioc distillé sec avec soluble (le 'DDCS'). Dans un essai de 28 jours, cent quarante-quatre (144) poussins de chair de la souche Arbor acre non sexés de 5 semaines (poids moyen de 1.09 ± 0.02 kg) ont été répartis au hasard dans quatre traitements diététiques d'abats de blé (WO) et DDCS (12% WO + 0% DDCS = 0% DDCS ; 8% WO + 4% DDCS = 4% DDCS ; 4% WO + 8% DDCS = 8% DDCS et 0% WO + 12% DDCS = 12 % DDCS) dans une conception complètement aléatoire. Chaque traitement comportait 2 répétitions de 18 oiseaux chacun. L'apport alimentaire en matière sèche (FI g / jour), le gain de poids quotidien (g / jour) et le gain de poids total (kg) diminuent avec l'augmentation des niveaux de DDCS, tandis que le taux de conversion alimentaire (FCR) augmente avec l'augmentation des niveaux de DDCS, respectivement. Cependant, il n'y avait aucune différence significative (P> 0.05) dans l'évaluation de la carcasse mesurée. Il a été conclu que le DDCS pouvait remplacer les abats de blé dans l'alimentation des poulets de chair jusqu'à 8% sans différence significative de croissance et de consommation alimentaire sans effets néfastes sur la qualité de la carcasse des oiseaux.

A study was carried out to evaluate the effect of replacing maize with sorghum and supplementation with enzymes, on the growth and laying performance of laying chickens. Four hundred and fifty 12-weeks old Lohman Brown pullets were distributed randomly into six dietary treatments with three replicates per treatment, each replicate had 25 birds with uniform group weights at the initial stage of the study. The treatments included maize without enzymes (T1) and sorghum without enzymes (T2) as two controls respectively, while T3, T4, T5, and T6 contained sorghum based diets with phytase, protease, roxazyme G2G, and a combination of protease and roxazyme G2G respectively. The experiment lasted from 12 to 32 weeks of age of birds during which data were collected on growth and early egg laying performance of birds. Data obtained were subjected to analysis of variance, using the completely randomized design (CRD). Significant differences among treatment means were compared using the Tukey test. Significant (p<0.05) differences were noted in final weight (g/bird), weight gain (g/bird), daily weight gain (g/bird), total feed intake (g/bird), daily feed intake (g/bird/day), and feed to gain ratio. Final weight and weight gain were significantly (p<0.05) better for birds in T4 (sorghum + protease) compared to the other treatments, but was similar to T1 (control). At the early laying stage, no definite trend was observed among the egg production traits. However, dietary treatment supplemented with phytase (T3) had the highest numerical values for; weight of first egg (54.28g), number of eggs at peak lay (24.00), hen house egg production 78.84%, and hen day egg production, 81.09%. It was concluded therefore, that sorghum with phytase and protease supplementations can be used in layers' diets for optimum egg production. It is recommended that phytase supplementation at 0.02% with sorghum can be incorporated into the diets of egg type chickens for optimum performance.

The effect of forage to concentrate ratios on the performance of weaner rabbits was investigated using twenty (20) weaner rabbits. They were randomly assigned to five treatment diets/with two replicates of two (2) rabbits per pen in a completely randomized design CRD). The experiment lasted for 56 days. Ti = forage 80%: concentrate 20%, T2 = forage 60%. concentrate 40%, T3 = forage 40%: concentrate 60%, T4 = forage 20%: concentrate 80% and T5 = forage 50%: concentrate 50% served as the control. Data were collected for feed intake, weight gain, carcass quality and the economics of the diet. The growth performance result was significantly different (p<0.05) for all the parameters considered except for total feed intake. Treatment 3 (T3) had the highest value for final weight (1423.0 g), total weight gain (925.5g) and daily weight gain (16.52 g), with the least feed conversion ratio of (2.58) among others. The cut parts results showed that there was significant difference (p<0.05) for all the parameters considered. 73 also had the highest value for the prime parts. The organ weights results did not follow any specific pattern that could be attributed to the effect of the test ingredients. The economics /gross margin showed that T3 was favoured among others A 731.38, N929.18, N1045.78, N828.81, N825.39),T3 (forage40%: concentrate 60%) was therefore recommended.

A 91 day feeding trial was conducted using twenty (20) weaned heterogeneous breed rabbits of both sexes with initial weight of 225g–500g to evaluate the replacement value of maize for composite cassava meal (CCM) in diet. Five experimental diets were formulated such that the control diet represented as treatment 1(T1) contained 100% maize as the major energy source in the diet. CCM replaced 25, 50, 75 and 100% of maize in the other treatments (T2, T3, T4 and T5 respectively). The rabbits were divided into five treatments of four rabbits each and randomly assigned to the five diets in a completely randomized design with each rabbit serving as replicate. Data collected included weight gain and feed intake, while feed conversion ratio and economics of production were computed. The result revealed that the crude protein (17.78-16.26%) and ether extract (6.79-5.93) content of the diet decreases as level of CCM increased in the diets while crude fibre (12.67-13.88%) content increased with increased level of CCM in the diet. The nutrient compositions of the experimental diets were within acceptable ranges for growing rabbits. The final weight and the total weight gain were not affected by treatment but feed intake significantly increased as the level of replacement increased indicating enhanced acceptability due to CCM in diet. Daily weight gain was also enhanced as the level of replacement of CCM for maize increased. The cost of feed per kg was reduced but the total cost of feeding was increased as the level of replacement increased. The cost of production was minimized and profit was maximized at 100%, when 100% of the maize was replaced by CCM. CCM has no harmful effect on performance of rabbits and the replacement of maize with CCM in diet has reduce the cost of feed per kilogram and maximize profit at 100% level of replacement. Farmers can include composite cassava meal in diet of rabbits to replace 100% of maize as major source of energy in diet.

Abstract Fattening refers to the proper management and feeding of livestock to achieve maximum weight gain at a minimum cost over a specified period of time. This study aimed to determine the most effective ratio of forage to concentrate on feed intake, performance, and carcasses of male Zel fattening lambs. The present study was performed using 20 lambs of 16-week-old for 90 days in a completely randomized design with four treatments and five replications at the Islamic Azad University of Qaemshahr. Experimental treatments included different ratios of forage to concentrate (80:20, 70:30, 60:40, and 50:50). Traits were measured during the fattening period. The collected data were analyzed by LSmeans procedure and regression in SAS software. Effect of different ratios of forage to concentrate was significant on all performance traits (p < 0.01), slaughter weight (p < 0.05), weight gain during rearing (p < 0.05), daily weight gain (p < 0.05), feed intake (p < 0.01), feed conversion ratio (p < 0.01), the weight of digestive system contents (p < 0.05), hot and cold carcass weight (p < 0.05), carcass percentage (p < 0.05) and thickness Backfat (p < 0.05). The linear change in the mentioned traits is due to the increase of the concentrate to forage ratio (p < 0.01). As the percentage of concentrate in the ration increases, feed intake increases. The concentrate is palatable and contains more energy and nutrients than forage. Therefore, lambs that consumed more concentrate had higher body weight and slaughter weight. Based on the results for optimal performance in fattening lambs, a ration with the ratio of forage to concentrate equal (50:50) is recommended.

An on-farm experiment was conducted in several villages in the district of Kupang, East Nusa Tenggara Province (NTT), Indonesia from June to October 2007. The experiment investigated the efficacy of a supplementation strategy to improve calf survival and performance during the dry season. A total of 258 Bali (Banteng, Bos javanicus) cow–calf pairs were used in the experiment. Calves from the 190 cow–calf pairs in the treatment groups were allocated grass hay + concentrate supplementation as follows: 1% (n = 98), 2% (n = 56) and 3% (n = 42) of calf bodyweight. There were 62 cow–calf pairs in the unsupplemented control group. The supplement consisted of grass hay and concentrate (rice bran, cornmeal, leucaena leaf and fish meal) containing 18% crude protein. The supplement was introduced to calves in the morning while confined to calf pens when the dams were grazing. Calves were reunited with the cows during the night. Parameters measured were calf mortality, calf and cow daily gain, and milk production. Supplementation tended to reduce calf mortality (P = 0.094) from 6.4% in control to 0% in calves receiving 2% and 3% supplement. Levels of supplementation significantly (P < 0.001) improved calf daily weight gain. Bodyweight changes and milk production of cows were unaffected by calf supplementation. It can be concluded that supplementation at 2% calf bodyweight reduces calf mortality and improves calf weight gain.
