Nutrition and suckling are largely recognised as the most important factors affecting postpartum period consequently reproductive efficiency of beef cattle. The aim this study was to evaluate effects body condition score (BCS) restriction with without presence calf on milk production, performance. Sixty-three crossbred (Angus × Hereford) multiparous cows were managed maintain different BCS at calving thereafter (low vs moderate; L, n = 31 M, 32). Within each group (L M) week 9 (66 ± 0.88...
Summary The aim of this study was to determine the effect nutrition during foetal and lactation periods on calf growth body composition, their association with changes in metabolic endocrine profiles first year life purebred (Hereford Angus) cross‐bred (F1) dam offspring. Forty calves dams (purebred – PU: Hereford Angus, CR: F1) were used a randomized block design factorial arrangement herbage allowance native pastures (high: Hi‐HA low: Lo‐HA), 4 vs. 2.5 kg dry matter/kg weight (BW) genotype...
The objective of this study was to evaluate the effect a short-term supplementation with rice bran (2 kg/cows/day) on endocrine and metabolic profiles hepatic gene expression, associated reproductive response in beef cows grazing conditions. Thirty-eight primiparous (Hereford, Angus Hereford × Angus) were used randomized block design according genotype, calving date body condition score at (BCS). At 64±14 days postpartum (day 0 experiment), assigned two nutritional treatments: i) control,...
Our objective was to evaluate the metabolic, endocrine and hepatic mRNA profiles through gestation–lactation cycle in purebred (PU: Angus Hereford) crossbred (CR: reciprocal F1 crosses) mutliparous beef cows (n=32), grazing on two herbage allowances of native pastures (2.5 v. 4 kg dry matter/kg BW; LO HI) their associations with cow's productive performance (calf birth weight, milk production commencement luteal activity). Cow BW, body condition score (BCS) blood samples were collected...
- This study investigated the effect of a supplement containing whole rice bran and crude glycerin for 21 days before mating on metabolic, productive, reproductive responses 28 primiparous suckling beef cows. Cows were randomly assigned to control group (CON, n = 14), grazing grasslands, supplemented (SUP, grasslands daily individually with 1 kg dry matter (DM) + 550 mL (224 g kg−1 DM methanol) per cow. After 33 natural mating, cows that had not expressed estrus subjected fixed-time...
The effect of shearing ewes at 50 days gestation on birth and weaning weight, vigour the lambs in first hour life survival single twin was investigated. Ultrasound pregnancy diagnosis used to allocate 140 Polwarth Day one four treatments, including two factors: time (prepartum (PS) postpartum (U)) litter size (single (S) (T)) resulting following treatments: single-bearing shorn (SPS, n = 39), unshorn (SU, 40), twin-bearing (TPS, 28) (TU, 33). All grazed together improved pastures. Body...
The research has shown the interesting contributions of shearing in mid-gestation on performance lambs from birth to weaning. Other studies have reported that at early pregnancy influences development placenta and lamb live weight birth. However, there was a lack information effect early-prepartum behavior offspring weaning onward. This study evaluated ewes 50 days gestation growth, reproductive response gastrointestinal parasite challenge female 18 months old. Fifty-seven Polwarth were...
Fifty-seven primiparous Angus, Hereford, and crossbred cows were used to study the effect of strategic supplementation on metabolic, productive, reproductive responses. The experiment had two periods including four phases: prepartum (phase I; 52 days), early postpartum II; 43 pre-mating III; 21 last phase mating, gestation, lactation until weaning IV; 103 days). Phases I II considered as period 1, phases III IV [...]
Research has shown the interesting contributions of shearing during mid or late gestation on performance lambs from birth to weaning. However, there is no information effects in first third pregnancy, well-being and productivity offspring adult life. The aim this study was investigate whether gestation, a critical time window for development placenta fetus, can influence live weight at parturition, weaning survival lambs. Additionally, it studied capable programming metabolic physiological...
