Abstract:
Sixty-four spring-calved primiparous crossbred cows paired by calving date and body condition score (BCS) at calving were used to study the effect of a short-term increase in the nutritional plane before the mating period on cow and calf performance, changes in metabolic and endocrine parameters and hepatic gene expression. At 48 ± 10 days postpartum (onset of nutritional treatment = day 0), cows were assigned to two treatments during 23 days: control (grazing of native pastures; NP; n = 31) and increased nutritional plane (NP improved with Lotus subbiflorous cv Rincon; IP; n = 33). Cow body weight (BW), BCS and total
protein and albumin concentrations increased while urea and non-esterified fatty acids levels decreased from the beginning of the nutritional treatment in both groups, indicating the animal positive energy balance as forage growth and availability of pastures increased during spring. In addition, cow BW and BCS, as well as calf average daily gain and BW, were greater in IP than in NP cows groups. Insulin concentrations were less in IP than in NP (1.37 vs. 2.25 ± 0.26 lU/ml) because insulin increased owing to nutritional treatment only in NP cows. Hepatic insulin receptor mRNA at day 23 tended to be 1.5-fold greater, while insulin growth factor binding protein-3 mRNA expression was 1.7-fold greater in NP than in IP cows. Reproductive responses were not affected by nutritional treatment, but days to initiation of ovarian ciclicity (108 ± 10 days) were positively correlated with insulin concentrations.
Grazing of improved NP for 23 days before the mating period did not improve cow reproductive performance but modified metabolic, endocrine and gene expression parameters, in agreement with greater nutrient and energy partitioning towards milk production, reflected in better calf performance.

ABSTRACT - This study investigated the effect of a supplement containing whole rice bran and crude glycerin for
21 days before mating on metabolic, productive, and reproductive responses of 28 primiparous suckling beef cows. Cows
were randomly assigned to a control group (CON, n = 14), grazing on grasslands, and a supplemented group (SUP, n = 14),
grazing on grasslands and supplemented daily individually with 1 kg dry matter (DM) of whole rice bran + 550 mL crude
glycerin (224 g kg?1 DM of methanol) per cow. After 33 days of natural mating, cows that had not expressed estrus were
subjected to a fixed-time artificial insemination protocol. Ten days after the insemination program, bulls were reintroduced for
21 days. Supplementation increased milk yield (SUP: 5.7±0.2 vs. CON: 5.0±0.2 kg d?1 ), milk protein content (SUP: 3.1±0.2
vs. CON: 2.8±0.2%), and body weight of cow (SUP: 379±2 vs. CON: 373±2 kg) and calf (SUP: 150±2 vs. CON: 142±2 kg).
Supplementation improved the energy balance, increased plasma concentrations of cholesterol (SUP: 223.2±6.4 vs. CON:
202.1±6.4 mg dL?1) and glucose (SUP: 72.0±1.2 vs. CON: 68.6±1.2 mg dL?1), and reduced non-esterified fatty acids
(SUP: 0.45±0.02 vs. CON: 0.56±0.02 mmol L?1 ). The percentage of cows on superficial anestrous after supplementation was
greater in SUP than in CON group (57 vs. 21%, respectively); however, no difference in final pregnancy rate was found
(SUP: 79 vs. CON: 64%). There was no evidence that the ingestion of crude glycerin with high content of methanol induced
clinical or hepatic disorders. Supplementation of whole rice bran and crude glycerin is not toxic, and can improve the energy
balance, reflecting in increase in milk yield and calf growth, with a slight effect on the reproductive activity- MenosABSTRACT - This study investigated the effect of a supplement containing whole rice bran and crude glycerin for
