Carcass traits and relative organ weights of growing rabbits fed graded levels of processed (ash treated and rumen liquor fermented) kola nut (Cola nitida) pod husks (PKPH) were investigated. One hundred and twenty (120) weaner rabbits of mixed breeds (New-Zealand white × Chinchilla) of equal sexes and average body weight 525.46g were randomly allotted to four (4) dietary treatments at 0 (0.00 % PKPH), 10 (10 % PKPH), 20 (20 % PKPH), and 30 % (30 % PKPH) inclusion levels and designated as diets 1, 2, 3, and 4, respectively. Each treatment group was replicated ten (10) times with three (3) rabbits per replicate and was fed ad-libitum for 56 days. The highest slaughter weight (1813.80 g/r), dressing weight (1068.70 g/r) and dressing percentage (58.54 %) recorded in rabbits fed diet 3 (20% PKPH) were similar to those fed the control diet (0 % PKPH) and diet 2 (10% PKPH) but was significantly (P<0.05) higher than those fed diet 4 (30 % PKPH). The lungs, liver, kidney, heart, and spleen of the rabbits fed dietary treatments were not significantly influenced. It was concluded that processed kolanut pod husk had no deleterious effect on carcass and relative organs weight of weaner rabbits.

This study aimed to evaluate the feeding behavior of Santa Inês ram lambs in the feedlot receiving diets without roughage in different amounts. Ten castrated Santa Inês male sheep with an average body weight of 20 kg and an average age of four months were used in the experiment. The following treatments were tested: T1 - animals receiving a diet ad libitum (FS100); T2 - animals receiving 95% of the amount of feed supplied in T1 (FS95); T3 - animals receiving 90% of the amount supplied in T1 (FS90); T4 - animals receiving 85% of the amount supplied in T1 (FS85); and T5 - animals receiving 80% of the amount supplied in T1 (FS80). A Latin square (5 × 5) design was adopted, using two simultaneous squares. The times spent feeding, ruminating, performing other activities; the total chewing time; and the number of periods spent feeding and on other activities changed with the reduction in the amount of feed supplied (P<0.05). Number of rumination chews per cud, time per cud, chewing speed, and time per rumination chew did not differ with the reduction of feed supply (P>0.05). Reducing the amount of feed provided to ram lambs consuming diets without roughage changes their feeding behavior.

Feeding trials were conducted to determine the significance of the reduction in feed consumption observed when growing pigs were fed complete diets containing approximately 6 ppm vomitoxin. Sixty Landrace weaners, weighing on average 22 kg, were randomly assigned to four dietary treatments. The dietary treatments were: (1) control cereal soybean diet fed ad libitum (mycotoxin free); (2) vomitoxin diet fed ad libitum in which 100% of the clean wheat included in the control diet was replaced by moldy wheat containing 10.32 ppm vomitoxin; (3) control diet fed restricted to the average daily intake of pigs fed the vomitoxin diet; and (4) upgraded vomitoxin diet fed ad libitum and containing approximately 20% more energy, crude protein, minerals and vitamins. Individual feed consumption was recorded daily for 12 wk. The control diet promoted significantly (P < 0.05) greater total body weight gains and also the greatest feed consumption. Body weight gains were not different (P > 0.05) for the vomitoxin and restricted control dietary treatments. The vomitoxin upgraded treatment resulted in greater total body weight gains (P < 0.05) than the vomitoxin treatment. During the 12-wk period, animals in the vomitoxin and restricted-control-fed groups consumed 71% as much feed as the control group fed ad libitum while the vomitoxin upgraded group consumed 77% as much as the control. Analysis for blood urea nitrogen, creatinine, plasma protein and alkaline phosphatase revealed no differences (P > 0.05) between dietary treatments. With respect to animal performance and blood biochemical profiles, the effect of vomitoxin appears to be primarily limited to feed acceptability and intake, with no apparent consequences on the metabolic function of the animal.

Feed formulation influence of forage (Caliandra calothyrsus, Gliricidia sepium and Penisetum sp.) on distribution protein in sheep digestive tractABSTRACT. It was assumed that feed formulation given to animals has an effect on digested nutrient of the animals. The purpose of this experiment is to investigate nutrient contribution mainly protein in digestive tracts of sheep by forage formulation treatment (Caliandra calothyrsus, Gliricidia sepium and Penisetum sp.). Thirty (30) sheep tails with the average body weight 15,42 kg (SD 2,68) were fed forage with the following formulation: A. Fresh Penisetum sp. (FP) and fresh Caliandra calothyrsus (FC) (7 : 3 or 70 % + 30 %), B. Fresh Penisetum sp. (FP) and fresh Gliricidia sepium (FG) (7 : 3 or 70 % + 30 %), C. Fresh Penisetum sp. (FP), fresh Caliandra calothyrsus (FC) and fresh Gliricidia sepium (FG). The experiment was conducted for 90 days and water was provided ad libitum. Parameter recorded in this experiment were distribution of protein in sheep digestive tract, covers by protein rate in rumen, omasum, abomasum, small intestine, caecum, large intestine and rectal. Data recorded were processed by covariant analysis with body weight of sheep at the early experiment treatment as a covariant. Continuation test with Tukey test. The results of this research indicated that treatment had no significant effect on protein distribution of digestive tract. It was shown by protein content in digestive tract had no significantly difference among treatments ( P 0,05), except for rectum part.

Feeding trials were conducted to evaluate the effect of including vomitoxin-contaminated wheat (VCW) containing 6.9 mg vomitoxin per kilogram in the complete diet of gilts during gestation and lactation (3 wk) and in the initial diet of weanling pigs up to approximately 23 kg liveweight. Four groups of four littermate gilts were assigned to four dietary treatments (one littermate per treatment) as follows: (1) control with 69% clean wheat (CW) in the diet with 16% crude protein; (2) 1/3 replacement of the CW with VCW; (3) 2/3 replacement of the CW with VCW; and (4) 100% replacement of the CW with the VCW. During gestation gilts were fed 2.3 kg/day of the diet in two meals, and the same diet ad libitum during lactation. The level of vomitoxin (VT) did not have any detrimental effect on body weight change of the gilt during gestation and after farrowing. Ad libitum feed consumption of the gilts during lactation was not significantly different among treatments. Litter size and weight at birth and at weaning time was not affected by the level of VT intake during gestation. One hundred and four weanling piglets (56 males and 48 females) weighing approximately 7.0 kg each were included in an 8-wk feeding trial. Four dietary treatments, including the control diet (treatment 1), contained 73.2% CW and 22% crude protein, and treatments 2, 3 and 4 in which VCW replaced 1/3, 2/3 and 100% CW, respectively. A significant (P < 0.05) reduction in body weight gain in the 8-wk period was observed only when 100% of the cereal included in the diet was VCW. This effect was due to a significant reduction in feed consumption of the piglets. Thus, feed efficiency was not affected by the level of VT content of the diet.

Abstract. A total of 238 Pannon White growing rabbits were slaughtered at 74, 84 and 94 days of age, at an average body weight of 2.53, 2.84 and 3.15 kg, respectively. Within each age group five body weight categories were formed in such a way that the weight difference between two neighbouring groups was equally 0.3 kg. The design of the experiment permitted the separate examination of the effects exerted by age and body weight on carcass traits and on meat chemical composition of the left hind leg (HL) and that of m. Longissimus dorsi (MLD). Dressing out percentage significantly increased with the increase of age in all body weight categories, as well as with the increase of body weight. The effect of age on the ratio of the fore part of the carcass depended on the body weight: significant difference was found in lower body weight categories. The ratio of the intermediate part of the carcass was not affected by age but it increased in rabbits of higher body weight. The ratio of the hind part of the carcass increased in older animals, while it decreased in rabbits of higher body weight, and this decrease was higher in older rabbits. The ratio of the perirenal fat to reference carcass significantly decreased with age in all body weight categories, but it significantly increased in rabbits of higher body weight. With the advancement of age the moisture content of the HL increased, while that of the MLD did not change. With the increase of body weight, moisture content decreased in both the HL and in the MLD. The fat content of both HL and MLD decreased in older animals, while it increased in rabbits of higher body weight.

The objectives of this investigation was to demonstrate that genotypes of calpastatin (CAST) Ser368Arg and ryadonide receptor 1 (RYR1) g.1843C>T may affect the carcass traits of pigs. Association analysis of the aforementioned SNPs was performed on 518 pigs included eight commercial crossbreeds and one pure pig breed. All pigs were slaughtered at average body weight of 113kg. Genotypes at the SNPs were determined by PCR-RFLP. There were found only two genotypes of RYR1 gene: CC (428 pigs) and CT (90 pigs) in this study. The effect of allele C compared to allele T on the higher fat content of pig carcass was confirmed. The allelic frequencies of allele 638Ser (C) and allele 638Arg (A) were 0.26 and 0.74, respectively. The significant association (P<0.05) was occurred between allele A and higher fat content, and between C allele and higher lean meat content. Our results showed no significant effect of the observed polymorphismSer638Arg on the intramuscular fat content or other indicators of carcass value.

AbstractA total of 360-day-old broiler chicks were allocated into six groups in 2 (Coccidial challenge or not) × 3 (dietary treatments) factorial design. Three dietary treatments including: basic diet, basic diet plus organic acids (OAs) in drinking water, and basic diet plus OAs in the feed with and without coccidial challenge. The OAs in water or feed improved (P < 0.01) average body weight (ABW), average body weight gain (ABWG), and feed conversion ratio (FCR) as compared with the control diet during starter, grower, and whole experimental period. Coccidial challenge decreased BW, ABWG, and average feed intake (AFI), as well as resulted in poor FCR during the starter and whole experimental period (P < 0.05). Though there was no interaction between OAs supplementation and coccidial challenge, the OAs supplementation improved the overall performance with and without coccidial challenge birds on 21 d and 35 d. IgG was found higher (P = 0.03) in broilers fed OAs in feed without the coccidial challenge group. On 18 d, OAs supplementation in feed increased TNF-γ (P = 0.006), whereas the coccidial challenge decreases TNF-γ (P = 0.01) and IL-10 (P =  < .0001), and increases IgM (P = 0.03), IgG (P = 0.04) and IgA (P = 0.02). On 29 d, the coccidial challenge increases IgM and IgA. On 18 d, jejunal lesion score was found significantly higher in the coccidial challenged group as compared to OAs supplementation with coccidial challenged groups on 18 d (P < 0.0001) and 29 d (P = 0.03). Crypt depth was higher, and Villus-height to Crypt depth ratio was lower in the coccidial challenge group on 18 and 29 d. The Goblet cells were found higher in the non-coccidial challenge on 18 d. After 18 d, 16S rDNA gene sequence analysis of ileal chyme has shown that coccidial challenge decreases Lactobacillus_reuteri species as compared to the non-challenged group (P = 0.02). After 29, Cyanobacteria abundance reduced (P = 0.014) in the challenged group than the non-challenged group at the phylum level. At the genus level, Lactobacillus (P = 0.036) and unidentified Cyanobacteria (P = 0.01) were found higher in the non-challenged group than the coccidial challenge group. The results indicate that the OAs supplementation showed improved responses in a pattern similar to the non-challenged control group by neutralizing the negative effects of the coccidial challenge.

This study was aimed to observe the requirements of non-phytate phosphorus (NPP) with phytase supplementation in starter phase broiler. A total number of 1000 broiler (500 males and 500 females) were divided into 5 dietary treatments for 21 days rearing period. The treatment diets (P1-P5) were basal diets with 0.67% Calcium (Ca) and 60 FTU phytase that combined with NPP at different levels, i.e.: 0.420% (P1); 0.345% (P2); 0.270% (P3); 0.195% (P4); 0.120% (P5). The basal diet was a corn-soybean based diet that contained 0.097% Ca and 0.124% Phosphorus (P). The data were subjected to a one-way ANOVA using complete randomized design. Response variables that observed in current study were: feed intake, nett gain, feed convertion ratio, average body weight, mortality and toe ash. Measurement of responses due to the reduction of NPP supplementation on average body weight and toe ash were then followed subsequently by generating equation for quadratic curve y = ax2+bx+c to determinate the NPP requirement. Determination of the maximum response was done through ymaks = -b/2a. Results showed that based on average body weight, estimation of NPP requirement with phytase supplementation were 0.317% for the 0-10 days; 0.314% for the 11-21 days; and 0.315% for the the 0-21 days rearing periods. Based on toe ash content, estimation of NPP requirement with phytase supplementation was 0.990% (toe) for the 21 days rearing period. This study was aimed to observe the requirements of non-phytate phosphorus (NPP) with phytase supplementation in starter phase broiler.
