And Performance

Eighteen multiparous periparturient Hariana cows (Bos indicus) (3-4 parity) in last month of their pregnancy were blocked into three groups (n=6) and fed for 30 days pre-partum to 30 days post-partum. The objective was to determine the effects of manipulating dietary cations and anions on hemato-biochemical profile, mineral metabolism and performance of cows. Nutrient requirements of cows were met by feeding concentrate and roughage. Varying levels of salt supplementation were used to formulate mineral mixture having DCAD of +11, +21 and +31 meq (Na+K - Cl+S) / 100 g of feed dry matter. Feeding DCAD of +11, +21 and +31 mEq/100 g of DM did not have any effect (P>0.05) on feed intake and body weight change during periparturient period. Blood calcium level was higher for the lowest DCAD (+11 meq/100 g of DM), suggesting that low DACD helps in mobilization of stored calcium in periparturient cows. pH of blood and urine increased curvilinearly with increasing DCAD and found maximum in +31 meq/100 g of DM DCAD fed group. Feeding of three different DCAD diets did not (P>0.05) have any effect on reproductive performance but milk yield was found significantly higher

Supplementation designed to increase the supply of glucose and amino acids, was compared with early weaning as strategies for reducing post-partum anoestrous in Bos indicusx Bos taurus (518x318) first-lactation heifers. Twenty-three pregnant heifers were allocated to four treatment groups and fed long-chopped hay (15.8 g N/kg dry matter) ad libitum and a complete mineral mixture throughout the experiment as well as 450 g molasses and 50 g urea per day during the final month of pregnancy. After calving, three groups were supplemented daily for 120 days with either 2 kg cracked rice (E), 0.4 kg formaldehyde-treated casein (P), or cracked rice (2 kg)+formaldehyde-treated casein (0.4 kg) (E+P); the unsupplemented control group had their calves weaned at 60 days post-partum. Supplemented animals had significantly higher intakes of hay (7- 1-7.3 v. 5.9 kg OM/day), weight gain (0.4-0.5 v. 0.0 kg/day) and body condition score (4.6-4.7 v. 4.3) than the unsupplemented heifers, but there were no differences between the supplemented groups in these variables. Unsupplemented animals and heifers fed P partitioned similar amounts of lactose and fat into milk, whereas secretion of both lactose and protein was significantly higher in the E+P and E groups. All control heifers ovulated within 14 days of their calves being weaned, whereas only two of the lactating supplemented heifers (EfP) showed cyclic ovarian activity at that time and three other lactating heifers ovulated several weeks later. The response to weaning occurred in heifers that had a liveweight and condition score of 374 kg and 4.3 respectively, which was 30-50 kg and a half unit in condition below the suckling heifers. In unsupplemented heifers showing ovarian cyclicity, acetate entry rate was less than half that of the supplemented animals, whereas glucose entry rate, adjusted for loss to lactose, was similar for both groups. Supplementation did not affect either the basal concentration or frequency of pulsatile release of luteinizing hormone (LH) at 60 days post-partum, or the LH response to gonadotrophin releasing hormone (5 8g GnRH). It is concluded that under the conditions of the present study, weaning had a greater effect than post-partum nutritional supplements on the resumption of ovarian activity in first-lactation heifers with moderate nutrition.

And Performance

A study was conducted to investigate the effects of Spondias mombin on milk composition using milk from twelve lactating West African dwarf (WAD) ewes. The lactating ewes were assigned to two treatment groups of six ewes per group, designated T1 and T2 representing control and trial group, respectively The ewes in T2, the trial group were fed Spondias mombin L. post partum while those in T1 the control were not fed Spondias mombin. Colostrum samples were collected from each ewe the first four days following parturition while normal milk was sampled for analysis after two weeks of lambing through 12 weeks of lactation. The constituents studied were lactose, milk protein, butterfat, ash, total solids and solid non-fat. Results showed that the colostrums of ewes fed S. mombin had significantly higher (P<0.05) total solids, and solids not fat contents of 18.34 and 11.31% respectively, than those of the control ewes which were 17.32 and 10.35%, respectively. The other constituents of colostrums of the different groups were not significantly different (P>0.05). At week 2 of lactation, lactose (3.98%) and ash (0.98%) concentrations of normal milk of treated ewes were significantly higher (P<0.05) than those of the control ewes for lactose (3.74%) and ash (0.65%). Also by the 12th week of lactation, ash contents of the two treatments were significantly different (P<0.05) with T2 having higher value. There were no significant differences (P>0.05) in the normal milk compositions of both groups in weeks 4, 6, 8 and 10. These results suggest that feeding S. mombin to lactating ewes could be useful in improving on the milk composition of WAD ewes and has no adverse effects on their general health and performance.

In early lactation dairy cows use stored body fat to provide an additional source of energy to support milk production and these reserves are replaced when energy requirements for milk synthesis are reduced. The extent to which body fat is mobilized depends on the nutritional state of the animal and its genetic potential. These changes are accompanied by substantial alterations in the intermediary metabolism of adipose tissue. The aim of this work was to investigate the timing and magnitude of changes in synthetic and lipolytic pathways in adipose tissue from dairy cows during a lactation cycle and at three levels of energy intake.Fifty four cows were fed grass silagead libitumand a concentrate ration at 3(L), 6(M) or 9(H) kg DM/day (Sutton et al 1992). An initial group of six cows was slaughtered at 2 to 4 dayspost partum(week 0) followed by two cows from each treatment at weeks 2, 5, 8, 11, 14, 19, 24 and 29.

Post-partum anoestrus is a primary contributor to low branding rates in Bos indicus cattle herds in the dry tropics of northern Australia [Entwistle, K. W. (1983). Australian Meat Research Committee Review No. 431. To increase branding rates, it was hypothesised that creep feeding for a short period in mid-late lactation during the latter half of the growing season may trigger an earlier onset of post-partum oestrus cycling, just as short-term, high-level, prepartum supplementation can achieve. Two experiments were conducted using Fn Brahman-cross cows (1/2, 5/8 and 3/4 crosses with Beef Shorthorn) which calved from late October to late Januarv. Cows were mated from mid-late Januarv to mid-April. Calves in one treatment in both experiments had ad libitum access to creep feed (calf pellets: 16% crude protein, 10 MJ ME/kg) for 4042 days from late February to early April. In experiment 2, the effects on cow growth and fertility due to supplementation with either cottonseed meal (1.5 kg/day) or molasses with 7.4% (w/w) urea for 49 days late in the dry season before calving ('spike' feeding) were also evaluated. Control cattle were unsupplemented. Creep feed was only consumed at 0.1 and 0.4 kg/day in experiments 1 and 2, respectively. Short-term creep feeding had no consistent effects on cow liveweights, condition, or fertility, or on calf growth and temperaments under extensive grazing conditions during the tropical wet season. Spike feeding reduced weight loss by 0.2-0.4 kg/day (P<0.01). The effects on liveweights did not persist into the wet season. There were no effects on cow fertility in this year of extreme weather conditions, when 4 months of nutritional and climatic stress followed supplementation.

This study assessed the effects of different amounts of supplement on the productive performance, nutrional caracteristics and behaviour of suckling beef calves, as well as on the productive performance of their dams on tropical pastures. Forty-four male Nellore beef calves with an average age of 120 days and an initial average body weight (BW) of 145±3.7 kg and their respective dams, with an average BW of 449±6.9 kg, were used. The amounts of supplement evaluated were as follows: 0 = calves received only mineral mixture ad libitum; 3, 6, and 9 = calves received 3, 6, or 9 g kg-1 BW of supplement, respectively, containing 250 g CP kg-1 (as-fed). The experimental design was completely randomized. A positive linear effect (P < 0.01) was observed in the intakes of dry matter and organic matter, and a cubic effect (P < 0.07) was observed for the intake of neutral detergent fiber corrected for ash and protein. There was quadratic effect (P < 0.06) for total digestibility of neutral detergent fiber. A cubic effect (P < 0.01) was observed for the calves’ performance. However, the calves’ supplementation did not affect the milk yield and performance (P ? 0.21) of their dams. The supplementation decreased grazing time (P < 0.01) but did not influence suckling time (P ? 0.59). It is recommended supplying of supplement containing 250 g CP kg-1 (as-fed) in amount 6 g kg-1 BW to suckling beef calves managed in tropical pasture. Supplementation of suckling beef calves increases the intake of dry matter, decreases grazing time and forage intake. However, it does not affect the suckling time and productive performance of their dams.
