Twenty-seven male Saanen kids were used in a completely randomized design to investigate the effect of feed restriction on retail and biological carcass yields, proportion of carcass retail cuts, carcass compactness, leg tissue composition, and ribeye area (REA). Animals were assigned to one of the following treatments: 0 (free access to feed: ad libitum), 30 or 60% of feed restriction. Initial body weight (BW) averaged 5 kg and animals were slaughtered when they reached 20 kg BW. Data were submitted to regression analysis as function of feed restriction. Feed restriction reduced carcass weight, retail cuts weight, and chump proportion and increased neck proportion. Bone proportion also increased while muscle tissue and fat proportion (including subcutaneous fat) decreased with feed restriction. Although REA and carcass compactness were both affected by feed restriction, they can be used to predict the proportion of carcass muscle. Carcass traits of Saanen kids were not negatively affected by 30% of feed restriction.

The objective of this study is to evaluate the influence of five feed restriction programs (FRP) on broiler performance and carcass yield. 425 Cobb 500® broilers were distributed in a completely randomized design with five FRPs and five replicates with 17 broilers. The FRPs were: Program 1 (P1): consumption ad libitum (AL) of control diet from 14 to 42 days; P2: quantitative restriction (QTR) of 10% of AL consumption from 14 to 28 days and AL consumption from 29 to 42 days; P3: AL consumption from 14 to 28 days and QTR from 29 to 42 days; P4: qualitative restriction (QLR) of 10% of the level of crude protein and essential amino acids from 14 to 28 days and AL consumption from 29 to 42 days; and P5: AL consumption from 14 to 28 days and QLR from 29 to 42 days. The broilers of the AL treatment gained more weight (p≤0.01), but had a similar FCR (P>0.05) compared to broilers submitted to QTR from 29 to 42 days. In addition, broilers fed QTR from 14 to 28 days presented a lower FI and a better FCR (p≤0.01) in relation to broilers fed QLR of 14 to 28 (P4) and 29 to 42 days (P5). The broilers fed QTR of 14 to 28 days diet presented a similar FCR as broilers fed AL. The 10% reduction in AL consumption of 14 to 28 d is a viable economical alternative to feed broilers up to 42 days of age.

UTILIZATION EFFECT OF COCONUT OIL IN RATION ON BODY WEIGHT, PERCENTAGES OF CARCASS AND ABDOMINAL FAT IN SUPER NATIVE HENS. This study was conducted to evaluate utilization effect of coconut oil in ration on body weight, percentages of carcass and abdominal fat in super native hens. This study was involving hundred unsexed super native hens at ages of eight weeks with the average initial body weight of 862.24 g ± 44.13 g. The treatments were ration without coconut oil (CO) utilization (R0), ration of 99.5% basal added with 0.5% CO (R1), ration of 99% basal added with 1% CO (R2), ration of 98.5% basal added with 1.5% CO (R3), and ration of 98.0% basal added with 2.0% CO (R4). The completely randomized design was applied as design with five treatments consisted of five replications at each treatment. Each experimental unit was put four heads of super native hens. The significant treatments were tested by Duncan’s test. Variables measured were life body weight, slaughter body weight, carcass weight and carcass percentage as well as abdominal percentage. Results showed that utilization effect of coconut oil in ration had the same effects on percentages carcassand abdominal fat, but had significant effect on life body weight and carcass weight. Therefore, it was concluded that utilizatilization of coconut oil up to 2 percents in ratio increased life body weight and carcass weight. Keyword: carcass weight, coconut oil, super native chicken.

The purpose of this study was to determine the relationship of broiler quail’s initial body weight which is fastened at post-hatch to growth and attainment the last body weight. One hundred thirty-five quails aged 12 post-hatch had kept in a cage plot which had prepared based on a completely randomized design with 3x3 factorial pattern and three replications which each replication consisted of 5 quails. The first factor is body weight post-hatch (B) consist of B1 = 5.1 – 6.0 g (light), B2 = 6.1 – 7.0 g (medium) and B3 = 7.1 – 8.0 g (heavy), the second factor is the duration of fasting post-hatch (P) consist of P1 = 24 hours, P2 = 36 hours and P3 = 48 hours. The observed parameters to fasting were feed consumption, body weight, and feed conversion. The result of this study is the quail with light early body weight (5.1-6 g) post hatch showed that the lightest last body weight is related to the value of feed conversion. Accession good performance of quail can be reached by access feed approximately 24 hours.

The aim of this study was to evaluate the feeding behavior of lambs fed diets containing peach palm meal replacing maize (0, 10, 40, 60, and 85% DM). Thirty Santa Inês sheep with an average initial body weight of 21.6 ± 0.87 kg were distributed in a completely randomized design with five diets and six replicates. Feeding time in min kg–1 DM and min kg–1 NDFap increased by 34 min and 99.6 min, respectively, with each level of substitution of maize for the peach palm meal. Rumination and chewing times, in min kg–1 DM and min kg–1 NDF, also increased in response to the substitution of maize for peach palm meal. When expressed in min day–1, rumination and chewing activities decreased by 12.4 and 14.6 min, respectively, as the amount of peach palm meal in the concentrate was increased. The time spent idle increased linearly (P < 0.05), by 14.6 min day–1, with the replacement levels, compared with the control diet. Peach palm meal in the composition of sheep diets reduces the intakes of dry matter and fiber and decreases the feed and rumination efficiencies. Replacing maize by peach palm meal increases the feeding time and rumination and chewing activities of feedlot lambs.

Abstract The objective in this study was to evaluate morphometric parameters of the ruminal papillae and intestinal villi of lambs fed diets containing Mimosa tenuiflora (Willd.) hay replacing Buffel grass (Cenchrus ciliaris L.) hay. Twenty-eight Santa Inês lambs with initial body weight of 20.3 ± 1.49 kg were used, being distributed in a completely randomized design with four treatments (0, 333, 670 and 1000 g/kg DM). The width of the ruminal papillae was not affected (P > 0.05), while their area linearly decreased (P = 0.01) as the level of M. tenuiflora hay increased. In the duodenum, the height (P < 0.0001) and the surface (P = 0.01) of the villi linearly decreased with the increase in the level of M. tenuiflora, while the width (P = 0.0001) and the area (P = 0.03) quadratically decreased with minimum values of 132.95 and 50,625.53 µm at the levels of 436 and 575 g/kg, respectively. There was a quadratic increase in the height of the jejunum villi (P < 0.0001) with a maximum value of 623.22 µm at the level of 333 g/kg, while the width quadratically decreased with a minimum value of 143.33 µm at the level of 526 g/kg and the area linearly decreased (P = 0.02). The height of the ileum villi (P = 0.0003) as well as the depth of the crypts in all segments (P < 0.001) linearly decreased. Therefore, it is suggested the substitution of C. ciliaris hay by M. tenuiflora hay up to 333 g/kg DM.

Normal young adult male rats were either force-fed or allowed to eat ad libitum a moderate carbohydrate diet for 3–4 weeks. The force-fed animals were given either the amount of diet consumed by the animals eating ad libitum (pair-fed) or 80% of this amount (underfed). After a 2-week period of observation, we found that the rats eating ad libitum gained 65 gm of body weight, the pair-fed, force-fed 62 gm and the underfed, force-fed 40 gm. On the basis of the water, fat and protein content of the skin, viscera and carcass of control animals killed at the beginning of the feeding regimen and of similar constituents of the experimental animals after 2 weeks of feeding, the composition of the newly formed tissues of the various groups of animals consisted of the following: a) the rat with free access to food—water = 67.8%, fat = 7.8% and protein = 22.4%; b) the pair-fed, force-fed animal—water = 55.5%, fat = 23.6% and protein = 17.7%; c) the underfed, force-fed animal—water = 64.4%, fat = 7.9% and protein = 20.0%. The ratio of calories retained in newly formed tissue to the calories ingested over the 2-week period was 11.9% for the animals eating ad libitum, 20.6% for the pair-fed, force-fed animals and 9.5% for the underfed, force-fed rats. Force feeding appears to change intermediary metabolic pathways in the direction of increased ‘efficiency’ with resultant greater fat deposition.
