Different Levels

summaryGrowth and visceral organ weights of male guinea fowl (Numida meleagris) given different levels of oxytetracycline have been studied in two experiments. In the first experiment 0, 5·0, 10·0, 15·0 and 20·0 mg oxytetracycline per kg diet were given to male guinea fowl from day 1 to 12 weeks. Body weight showed significant (P < 0·05) increases with incremental levels of the antibiotic up to 10 mg/kg diet. No further increases in growth were recorded with supplementation above this level. There were no treatment effects on the gizzard, lungs and male reproductive organs. Only the heart, liver and intestine weights were significantly (P < 0·05) affected by the treatment, and then only at the highest (20 mg/kg) of the inclusion rates examined. A second experiment was conducted to find out if the growth response obtained with 10 mg/kg oxytetracycline could be produced with a smaller dose. This was achieved at 6·6 mg/kg.

The effect of feeding recommended levels of three antibiotics on the visceral organs of growing guinea fowls has been examined. Day old broiler type guinea fowls were given Oxytetracycline, Rocaryone, and zinc bacitracin supplemented diet till 12 weeks of age. Dressed weight of medicated guineas were significantly higher than controls. No treatment effects were observed on the lungs, gizzards and reproductive organs. Fat pads were significantly (P.05) heavier in treated birds as compared with controls. Heart and liver weights were also significantly higher (P.05) in treated guinea fowls.

Abstract The objective of this study was to determine the interactive effects of dietary fiber source and lipid source on growth performance and visceral organ weights of weaned pigs. Two hundred and eighty 21 days old pigs [initial body weight (BW) = 6.84 kg] were housed in 40 pens (7 pigs/pen). The pigs were fed 4 diets (10 pens/diet) in a randomized complete block design in 2 phases, Phase 1 from day 0 to 14 and Phase 2 from day 14 to 35. The diets were corn-soybean meal-based with either sugar beet pulp (SBP) or soybean hulls (SBH) as fiber source and either soybean oil (SBO) or choice white grease (CWG) as fat source in 2 × 2 factorial arrangement. The BW and feed intake were determined by phase, whereas visceral organ weights were determined on day 35. Fiber source and fat source did not interact on growth performance and organ weights relative to BW. Pigs fed CWG-containing diets had lower (P &lt; 0.05) gain to feed ratio than those fed SBO-containing diets by 7.95% during Phase 1 of feeding. Pigs fed SBP-containing diets had lower (P &lt; 0.05) gain to feed ratio than those fed SBH-containing diets by 7.94% during Phase 1 of feeding. However, pigs fed SBP-containing diets had greater (P &lt; 0.05) stomach weight, and tended to have greater (P &lt; 0.1) heart, small intestine and large intestine weights relative to BW than those fed SBO-containing diets. In conclusion, replacement of SBH with SBP in diets for weaned pigs reduced feed efficiency and increased visceral organ weights relative to BW, implying that the replacement of SBH with SBP in diets of weaned pigs increased energy expenditure in visceral organs. Inclusion of SBO (at the expense of CWG) in diets for weaned pigs can improve feed efficiency.

Eight generations of Yorkshire swine and seven generations of Hampshire swine, involving a total of 2300 animals of which 1350 were selected for reduced backfat thickness and increased growth rate, had concurrent increases in visceral organ weights (heart, lungs, spleen, liver and kidney). Implications are that this could amount to 0.4 kg less weight per carcass. Key words: Pigs, organs, selection, Yorkshire, Hampshire

Abstract Objective of this study was to determine the interactive effects of dietary fiber solubility and lipid source on growth performance, visceral organ weights, gut histology, and gut microbiota composition of weaned pigs. A total of 280 nursery pigs [initial body weight (BW) = 6.84 kg] weaned at 21 d were housed in 40 pens (7 pigs/pen). The pigs were fed four diets (10 pens/diet) in a randomized complete block design in two phases; Phase 1 from 0 to 2 weeks and Phase 2 from 2 to 5 wk. The diets were corn-soybean meal-based with either sugar beet pulp (SBP) or soybean hulls (SBH) as a fiber source and either soybean oil (SBO) or choice white grease (CWG) as a lipid source in a 2 × 2 factorial arrangement. The BW and feed intake were determined by phase, whereas visceral organ weights, intestinal histology, and gut microbial composition were determined at the end of the trial. Dietary fiber solubility and lipid source did not interact (P &gt; 0.05) on average daily feed intake and average daily gain across all phases. However, the gain to feed ratio (G:F) for CWG-containing diets was lower (P &lt; 0.05) than that for SBO-containing diets for Phase 1. Also, G:F for SBP-containing diets was lower (P &lt; 0.05) than that for SBH-containing diets for Phase 1 and for the entire study period. Pigs fed SBP-containing diets had greater (P &lt; 0.05) stomach weight, and tended to have greater (P &lt; 0.10) small and large intestine weights relative to BW than those fed SBH-containing diets. Duodenal villous height to crypt depth ratio for CWG-based diets tended be greater (P = 0.09) than that for SBO-based diets. Fiber solubility and lipid source interacted (P &lt; 0.05) on relative abundance of Bacteroides in the colon such that the relative abundance of the Bacteroides for CWG was greater (P &lt; 0.05) than that for the SBO in SBP-based diet, but not in SBH-based diet. Relative abundance of Butyricicoccus in the colon for SBH-based diet was greater (P &lt; 0.05) than that for SBP-based diet. In conclusion, inclusion of SBH instead of SBP in corn-soybean meal-based diets for weaned pigs can result in increased feed efficiency and relative abundance of Butyricicoccus in the colon, which is associated with improved gut health. Also, inclusion of SBO instead of CWG in the diets for weaned pigs can result in improved feed efficiency during Phase 1 feeding; however, the pigs may recover from the low feed efficiency induced by dietary inclusion of CWG instead of SBO after Phase 1 feeding.

Effects of castration on growth rate, body and visceral organ weights of pigs were investi­gated using data from intact males, intact females of Large White pigs full or half cast­rated at 2, 4, or 6 weeks of age. Body weights and feed intake were recorded to the nearest 0.1kg at weekly intervals from birth, while weights of abdominal and thoracic organs were taken at slaughter. Results show that age at castration signi­ficantly affected weaning weights and weights at 2 months of age (P < 0.05), but did not affect the weights of visceral organs and the average daily weight gain (P> 0.05). Castration significantly affected weaning weights (P <0.05) average daily gain (P <0.01), body weights at 4 months (P <0.05), but not the weights of the visceral organs (P> 0.05) Intact females and, intact males significant­ly differed in body weights at 4 months and in average daily weight gain (P 0.05). Com­parisons between full castrates and intact males showed significant differences in all the measured parameters except the weights of visceral organs. Full castrates and intact females did not differ, significantly (P > 0.05) in any of the traits measured.

ABSTRACT The effect of subcutaneous administration of graded doses of C19 (androstene or androstane) steroids on serum levels of LH and FSH and on weights of accessory reproductive organs in gonadectomized, adult male rats were investigated. The C19 steroids were administered during 7 days in doses of 100, 50, 25, 12.5 or 6.25 μg per 100 g body weight per day. With the amounts of steroids used, 5α-dihydrotestosterone and 5α-androstane-3α,17β-diol had a high potency in preventing the rise of serum gonadotrophin concentrations and in curbing the decrease of weights of ventral prostates and seminal vesicles following orchidectomy. 5α-Androstane-3β,17β-diol showed no such effects. Positive feedback effects on serum gonadotrophins in castrates were observed following injection of certain doses of some steroids. Effects of steroids on accessory reproductive organs did not always correlate with those on gonadotrophic function of the hypothalamic-pituitary unit.

Parakeets (Melopsittacus undulates) are classified parrot order Psittaciformes. Parakeets are monomorphic birds whose sex is difficult to be distinguished. Sex identification is very important for breeding efforts in order to increase the parakeet population. External morphology was determined to identify the sex of the birds. This research was conducted to determine the sex of parakeets (male and female). This study used five male and five female parakeets aged 4 months as the study objects. This study used the quantitative and qualitative method. Results of this study was verified by performing surgery to determine the sex of parakeet based on their reproductive organs. The t-test results of morphometric characteristics showed no significant different in the length of body, upper bill, lower bill, wing, tail, femur, tibial-tarsus, tarsometatarsus and digits as well as the body weight between male and female parakeets.  The color of the cere was useful to accurately determine sex in parakeets (blue in males and white in females). This research provided information to the public about the differences between male and female parakeets for the selection of good broodstock in order to increase their population in captivity.
