Crossbred New Zealand White meat type 8 male and 16 female rabbits aged 3.5 to 4.5 months weighing 9.5 to 13.0 kg were used in a 128 day trial to study the effects of concentrate supplementation on growth and reproductive performance of rabbit under rural condition. Rabbits were divided according to live weight into two treatment groups, i.e. T1 (conventional diet) and T2 (conventional diet + concentrate 75 g/d per rabbit) with four replications per treatment in a Complete Randomized Design (CRD). All animals had free access to locally available green grasses. Results showed that, average daily live weight gain was significantly (p < 0.01) higher in T2 (13.02 ± 0.43 g/d) than T1 (5.30 ± 0.43 g/d) group. Litter weight at birth was better (p < 0.05) in T2 (180.38 ± 16.37g) than T1 (137.19 ± 16.37g) group. Litter size at weaning differed (p < 0.05) and the mean values were 1.37 ± 0.30 for T1 and 2.37 ± 0.27 for T2 group. Kit weight at weaning was superior (p < 0.01) in T2 (408.12 ± 3.85g) than T1 (310.62  ± 3.56g) group. Kit mortality up to weaning was higher (p < 0.01) in T1 (45.0 ± 10.07 %) than T2 (26.92 ± 10.7 %) group. These results indicate that, supplementation of concentrate in addition to conventional feeding may improve growth and reproductive performance of rabbit under rural condition.  Key words: Crossbred, New Zealand White rabbit, reproductive performance, growth, concentrate DOI = 10.3329/bjvm.v4i2.1296 Bangl.

ABSTRACTThe effects of high-low (HL) and low-high (LH) patterns of nutrition during the 5 weeks prior to a synchronized mating were studied on the reproductive performance of 115 Welsh Mountain and 114 Brecknock Cheviot ewes in a range of body condition at the start of treatment. For 2 months prior to treatment imposition, ewes were grazed in a systematic way at different stocking rates on different sward heights to obtain a range of body condition scores. Target score groupings were 2·00 to 2·25, 2·50 to 2·75 and 3·00 to 3·25 and although scores of 1·50 to 3·25 were obtained, most lay in the 2·00 to 2·75 range. Two treatment groups, balanced for live weight and body condition score, received high and low levels of nutrition for 16 days from mid October, achieved, respectively, by a low stocking rate on a sward with a high surface height plus ad libitum concentrate and a high stocking rate on a sward with a low surface height plus 200 g hay per head per day. Treatments were then reversed for the 17 days prior to mating. Live-weight and body condition-score changes were recorded and reproductive performance at first mating was measured from counts of corpora lutea and viable embryos at slaughter either at return to service or at 4 weeks after first mating. There were no differences due to nutritional pattern in live weight or body condition score at mating. The LH treatment significantly increased the rates of ovulation, conception, multiple ova survival and potential lambing per ewe pregnant and per ewe mated in the Welsh Mountain breed but significantly increased only the rates of ovulation and potential lambing per ewe pregnant in the Brecknock Cheviot breed compared with the HL treatment. The relatively poorer response in the latter breed was partially due to a lower ovulation rate potential coupled with non-significantly lower rates of conception and survival of single-shed ova associated with the LH treatment. Much of this relatively poorer reproductive performance in the Brecknock Cheviot breed was in ewes with body condition scores 3= 2·75. Reproductive performance increased with increasing body condition at the start of treatment over the range of scores =≤ 2·25 to 2·50 in both breeds and, while continuing to improve in scores above 2·50 in the Welsh Mountain breed, in the Brecknock Cheviot breed it started to decline. Ewes with a body condition score of 2·50 in both breeds showed the greatest response in potential lambing rate to the LH treatment.

1. Twelve sets of 3 litter-sister Large White gilts were mated at first oestrus after reaching 250 lb. live-weight and given daily during 3 successive pregnancies either 6 lb. (A), 3 lb. (B) or 3 lb. for 76 days then 6 lb. until parturition (C) of the same meal mixture. During an 8-week lactation all were given 4 lb. meal plus 0·8 lb. per piglet suckled.2. There was a significant linear increase in numbers born with successive parities (P<0·05) but no significant differences between treatment or sister groups. There was a highly significant difference between treatment groups in mean piglet birth weight (P< 0·001) but no parity effect; mean birth weights were 2·76, 2·40 and 2·58 Ib. for Groups A, B and C respectively. Differences between sister groups in mean piglet birth weight were also significant (P<0·05).3. Post-natal litter performance was poor for all groups, probably because of the presence of E. coli, but there was no evidence of treatment effects other than on 3-week weight of third litters, which was significantly greater in Group C than in A or B (P<0·05). There were no significant effects on either number or weight of piglets at 8 weeks.

An experiment was conducted with 24 buck and 24 doe rabbits of about 5-8 months. The animals were fed diets containing garlic flour meal to determine the effect on the hormonal profile and reproductive performance of the rabbits. The 48 rabbits were separated according to their sexes (buck and doe) and divided into four treatment groups with four rabbits consequently replicated three times in a completely randomized design. Dietary levels of 0.0, 5.0, 10.0 and 15.0% of garlic flour meal were used to formulate the diet for rabbits. At the end of this trial, different parameters on hormonal profile and reproductive performance were determined. All the parameters of hormonal profile were significantly P<0.05) different thereby maintaining similar values except luteinizing hormone which had slight value fluctuation. The highest value of testosterone and progesterone were recorded in the diet containing 15.0% garlic flour meal. Similarly, the parameters on reproductive performance exhibited significant (P<0.05) difference. Partum weight and litter weight at birth showed a higher value as garlic meal was increased. The results of this study indicated that 15.0% dietary level of garlic flour meal proved acceptable for hormonal profile and reproductive performance of rabbit.

Six hundred day-old unsexed broiler chicks were used in a 42-day trial to compare the effects of different levels of palm oil supplementation on feed intake, weight gain, feed conversion and carcass quality of broilers. The chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. Each treatment had 150 broilers with 50 broilers per replicate. Four diets were formulated using locally available ingredients as diet without oil, diets containing 2.5%, 3.0% and 3.5% palm oil. All broilers had free access to ad libitum feeding. Results indicated that, supplementation of diets with different levels of palm oil significantly (p<0.05) influenced feed intake of broiler only at the age of 6th week. It was observed that as the level of supplementation increased, feed intake gradually decreased up to 6th week. Supplementation of diets with different levels of palm oil increased live weight gain of broilers. Differences (p<0.01) were observed at the end of 4th, 5th and 6th weeks of age only. Use of different levels of palm oil significantly (p<0.05) changed blood weight, heart weight and dressed weight. Survivability of broilers was higher in the supplemented group compared with without oil group. It was concluded that, supplementation of palm oil at 3.5% level in the diet of broilers resulted higher weight gain, better feed conversion and improved carcass characteristics comparing other levels. It may be concluded that supplementation of palm oil at 3.5% level in the diet of broilers resulted significantly (p>0.05) higher feed conversion ratio compared to 2.5% and 3.0% levels.DOI: http://dx.doi.org/10.3329/bjas.v43i1.19384 Bang.

Some recent studies (Frutos et al, 1992; Giraldez et al, 1993) comparing Spanish sheep breeds have indicate possible differences between breeds in the digestive diet utilization. The aim of this study was to compare voluntary food intake and diet digestibility in three sheep breeds when offered three levels of concentrate supplementation.A latin square trial (3x3x3) involving three sheep breeds and three levels of concentrate in three periods, with three replicates was designed. The breeds compared were Merina (39.83±10.05 kg live weight (LW)), Churra (44.33±9.86 kg LW) and Assaf (55.83±7.65 kg LW) and three non-productive ewes of each breed were used. All animals were divided into three groups of three animals (one ewe per breed) and housed in individual pens with free access to water and mineral blocks.

Objetivou-se avaliar o efeito dos níveis de suplementação sobre o desempenho de bovinos em sistema de terminação no período das águas em pastagem de capim Panicum maximum cv. Mombaça e sua viabilidade econômica. No experimento foram utilizados 68 bovinos não castrados da raça Nelore, sendo conduzido segundo delineamento inteiramente casualizado, com dois níveis de suplementação de concentrado na proporção de 1,2% e 1,8% peso vivo (PV) com base na matéria seca (MS). Os níveis de suplementação não diferiram nos pesos corporais dos animais nas pesagens feitas durante o experimento e final. Os animais suplementados com 1,8% do PV obtiveram maior ganho de peso total, área de olho de lombo final e espessura de gordura subcutâneo final. Os níveis de suplemento não influenciaram significativamente no peso de carcaça quente, conformação da carcaça e rendimento da carcaça. Os animais que receberam o maior nível de suplementação tiveram maior acabamento da carcaça. O maior nível de suplementação gerou maior custo inicial, médio, final e maior custo por ganho de peso dos animais. Assim, a suplementação com 1,2% do PV resulta em menor custo por quilo de carne produzida, sendo o mais indicado para bovinos terminados a pasto.Palavras-chave: análise econômica, confinamento a pasto, Panicum maximum cv.

Mombasa and its economic viability. In the experiment, 68 Nellore bulls were used, and were conducted in a completely randomized design with two levels of concentrate supplementation at the ratio of 1.2% and 1.8% live weight (LW) based on the dry matter (DM). Supplementation levels did not differ in body weights of animals during weighing done during the experiment and final. The animals supplemented with 1.8% of the LW obtained greater total weight gain, final loin eye area and final subcutaneous fat thickness. Supplement levels did not significantly influence hot carcass weight, carcass conformation, and carcass yield. The animals that received the highest level of supplementation had a better finishing of the carcass. The higher level of supplementation generated higher initial, average, final cost and higher cost for weight gain of the animals. Thus, the supplementation with 1.2% of the LW results in a lower cost per kilogram of meat produced, being the most suitable for beef cattle.Keywords: economic analysis, feedlot in pasture, Panicum maximum cv.
