The objective of this study was to evaluate the effects of dietary energy levels on growth performance, rumen fermentation and bacterial community, and meat quality of Holstein-Friesians bulls slaughtered at different ages. Thirty-six Holstein-Friesians bulls (17 months of age) were divided into a 3 × 3 factorial experiment with three energy levels (LE, ME and HE; metabolizable energy is 10.12, 10.90 and 11.68 MJ/kg, respectively) of diets, and three slaughter ages (20, 23 and 26 months). Results indicated that bulls fed with ME and HE diets had higher dry matter intake, average daily gain, and dressing percentage at 23 or 26 months of age. The ME and HE diets also reduced bacterial diversity, altered relative abundances of bacteria and produced lower concentrations of acetate, but higher butyrate and valerate concentrations in rumen fluid. Increasing in dietary energy and slaughter age increased the intramuscular fat (IMF) and water holding capacity. In summary, Holstein-Friesians bulls fed with ME and HE diets, slaughtered at 23 and 26 months of age could be a good choice to produce beef with high IMF. Slaughter age may have less influence than dietary energy in altering fermentation by increasing amylolytic bacteria and decreasing cellulolytic bacteria, and thus, further affecting meat quality.

Abstract Fifty-six litters standardized to 12 piglets from first-parity sows were used to determine the effects of creep and nursery diet compositions on pre- and post-weaning pig growth performance. At three days of age, litters (initial BW 2.31±0.61kg) were assigned to one of four creep feeding regimens (n=14): [1] commercial creep feed (COM), [2] liquid milk replacer (LMR), [3] pelleted milk replacer (PMR), or [4] no creep feed (NO); creep feeds contained 1.0% brilliant blue as a fecal marker. Fecal swabs were collected every 3±1 days to identify piglets that regularly consumed creep feed. At weaning (18±1 days of age), six pigs per litter that consumed creep feed were placed on either a HIGH- (contained highly digestible animal proteins) or LOW- (contained corn and soybean meal as the main protein sources) quality nursery diet (n = 7) in a three-phase feeding program over 38 days. The LMR disappeared at the greatest rate (37.7 g/pig/d; DM-basis) versus COM and PMR (10.8±1.5 g/pig/d; P < 0.001). Litters that received LMR had the greatest proportion of pigs with blue fecal swabs between study days 4 and 15 (85.0 vs 59.0±0.4%; P < 0.05) and LMR piglets had greater BW at weaning versus all other treatments (6.32, 6.02, 5.92, 5.67±0.14 kg, for LMR, COM, NO, and PMR, respectively; P < 0.001). Over the entire nursery period, pigs that received LOW diets had reduced ADG (399 vs 485±42 g; P < 0.001), ADFI (520 vs 595±37 g; P< 0.001), G:F (0.77 vs 0.82±0.03; P < 0.01), and BW at the end of the nursery period (21.2 vs 24.4±1.6 kg; P < 0.001), with no carryover effects of creep feeding regimen. Providing supplemental nutrition during the suckling period via LMR improved pig body weight at weaning, but did not improve post-weaning growth performance, regardless of nursery diet quality.

The aim of this study was to determine growth performance until weaning age of Honamli goat kids reared in extensive conditions in Turkey. Study was carried out with 75 Honamli kids (44 female, 31 male), kept at the Research and Training Farm of the Faculty of Veterinary Medicine of Mehmet Akif Ersoy University in Burdur, Turkey. Birth weight of male kids was higher than that female kids and also birth weight of single kids was higher than that twin kids. Live weight in the 120th day of male, female, single and twin kids were 24.4 kg, 22.0 kg, 26.9 kg and 21.2 kg, respectively. Withers height, body length, chest circumference and nose length on the 120th day were detected as 61.6 cm, 58.4 cm, 59.2 cm and 18.4 cm, respectively in female Honamli kids. Same measurements were 63.9 cm, 61.7 cm, 62.7 cm and 20.0 cm for males Honamli kids.
