A study was conducted in adopted villages of KVK Bundi to assess the effect of supplementing shatavari (Asparagus racemosus) feed on performance of lactating buffaloes. Twenty lactating buffaloes in mid lactation with similar age, body weight and milk yield were selected from dairy farms of the local farmers and divided into two groups of ten animals each. Control group was maintained as per farmer's practices (feeding of 3 kg cotton seed cake along with wheat straw), while groups comprising feeding of wheat straw + shatavari powder 50gm /day /animal up to 60 days. Result revealed that 19.67 per cent higher average milk yield was recorded in buffaloes feeding under group (7.36 kg/day) as compared to (6.15 kg/day). Increase in the income by feeding Shatavari came to Rs. 50.50/day/animal. It was concluded that feeding of Shatavari along with wheat straw improves milk yield and fat percent as well as reproductive performance in lactating buffaloes.

The objective of this study was to determine the effects of the administration of recombinant bovine somatotropin (rbST) throughout lactation to high-yielding subfertile (conception > 270 days postpartum) Holstein cows undergoing extended lactations (≥480 d) on milk production and reproductive performance. The study used two large adjacent commercial herds with similar management in a hot area of northern Mexico (25° N). Cows in one herd (n=2341) received a 500-mg dose of rbST every 14 d until dried off, starting 60 days postpartum. The other herd served as control (n=984). Across parity, rbST-treated cows produced 20% greater milk yield than control cows in 305-d lactations. Across parities, milk yield from 305 d postpartum to the end of lactation was 2734 kg higher in rbST-treated cows than control cows. Across parities rbST-treated cows produced 4777 more kg of milk during the entire lactation (mean 605 d) than the control group (mean 572 d). Conception rates (CR) at first service were only 3.2% and 5.9% (p<0.05) for control and rbST-treated cows, respectively. Overall CR was 43.5% and 61.6% (p<0.05) for control and treated cows, respectively. Control cows required 2.4 more (p<0.01) services per conception than rbST-treated cows. It was concluded that in this hot environment, the use of rbST suits dairy producers because it substantially improves both milk yield and reproductive performance in subfertile high-yielding Holstein cows. By markedly increasing lactation length and lactation persistency farm efficiency is greatly improved due to extended herd life.

Key Factor

Fertility in dairy cows has decreased over the last fifty years while milk production per cow has increased. Furthermore, dairy herds become larger resulting in fewer employees per cow, which might also influence reproductive performance. To elucidate the situation in Germany, selected parameters (conception rate, service rate, pregnancy rate, days to first insemination and days open) were studied using data on 148 herds. For statistical analysis the herds were categorized concerning milk yield: (1) &lt; 30 kg, (2) 30‒35 kg, and (3) &gt; 35 kg/cow/day as well as concerning herd size: (1) &lt; 200, (2) 200‒400, (3) 400‒1000 and (4) &gt; 1000 milking cows. There was no difference in conception rate among herds. That means on dairy farms of larger size or with high milk yield the chance of an inseminated cow to become pregnant is the same as in small herds or in herds with low milk yield. Small herds (&lt; 200 cows) had lower pregnancy rates than larger herds (200–400 cows). The pregnancy rate in herds with different milk yield was not statistically different. Though there was a trend that dairy farms with higher milk yield (&gt; 30 kg) had higher pregnancy rates. The statistical differences and trends of pregnancy rates are due to higher service rate in larger herds as well as in herds with high milk yield. Therefore, service rate is the key factor for high reproductive performance on dairy farms. Poor fertility is not associated with high milk yield on herd basis or large herd size but may represent inappropriate farm management.

Although it has become increasingly clear that fertility in modern dairy cattle is declining in association with increased milk yields, the underlying mechanism is poorly understood. The first ovulation post partum is delayed in dairy cows undergoing selection for genetic merit for milk yield in association with lower circulating insulin concentrations. The aim of this study was to investigate whether feeding a diet to increase circulating insulin concentrations can overcome this delay in the first ovulation post partum. The experiment was a 2 x 2 factorial design (n = 10 per group) involving diet and genetic merit for milk yield. The dietary treatment started on the day of calving and lasted for 50 days. Plasma samples were collected each day and ovarian ultra-sonography was performed three times a week during the experimental feeding period. Milk yield was recorded each day, and body weight and body condition score were determined each week. Milk samples were collected three times a week from day 50 to day 105 post partum, and reproductive performance data were recorded for all the cows as part of the routine farm practice. The dietary treatment induced significant differences in plasma insulin concentrations in both high and low genetic merit cows. Although high genetic merit cows produced more milk, lost more body weight and had lower body condition scores during the experiment, no significant effect of diet was observed on these measurements. The high insulin inducing diet increased the proportion of cows ovulating within 50 days of calving and reduced the intervals from calving to first ovulation, and tended to reduce the intervals from calving to first service and to conception. These fertility parameters were also more favourable in low than in high genetic merit cows, but no interaction between diet and genetic merit was observed for any of these parameters. Genetic merit, but not diet, also affected the number of services required per conception and the conception rate. In conclusion, these results have confirmed that genetic selection for high milk yield is associated with a decrease in reproductive performance in dairy cows. More importantly, this study has demonstrated that it is possible to alleviate this problem by nutritional manipulation.

Anaerobic fungi were orally dosed to lactating buffaloes to study their effect on the digestibility of a diet (composed of 50% wheat straw and 50% concentrate along with six kg maize green/animal/day), rumen fermentation patterns and milk production. Group I (control) was administered with fungus-free anaerobic broth, while group II and III were administered with Orpinomyces sp. C-14 or Piromyces sp. WNG-12 (250 ml; 3-5 days of growth/animal/ week), respectively. Milk production was higher in group II and III (8.42 and 8.48 kg/d) than in the control (8.03 kg/d) with virtually the same feed intake (i.e. 11.50 and 10.62 and 11.79 kg, respectively). There was an increase of 6% fat-corrected milk yield/animal/day in group II and III, respectively compared to the control. The milk fat was higher in the fungal culture administered groups than in the control group. The digestibility of dry matter, crude protein, neutral detergent fibre, acid detergent fibre, cellulose and digestible energy also increased significantly in group II and III. The pH and ammonia nitrogen were lower, whereas total volatile fatty acids, total nitrogen, trichloroacid precipitable nitrogen and number of zoospores/ml of rumen liquor were higher in group II and III when compared to the control. Hence, it can be stated that rumen fungi can be used as a direct-fed microbial in lactating buffaloes, to enhance the digestibility of wheat straw based diets leading to higher production.

The study was conducted to determine the effects of vitamin E on reproductive performance in mice treated with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The 75 female and 40 male mice were randomly assigned into five groups. The levels of both TCDD and vitamin E given by gavage were 0 and 0 (Control group), 100 and 0 (experimental group I), 100 and 20 (experimental group II), 100 and 100 (experimental group III), and 100 ng/kg/day and 500 mg/kg/day (experimental group IV), respectively. Males and females were mixed to mate at the ratio of 1:2 after 4-week experiment. The gavage treatments were continued until the end of gestation in female mice after mating. The results showed that the litter number, survival rate, and body weight at birth of offspring in experimental group I had significantly decreased, and the females’ pregnancy rate and pup sex ratio in experimental group I had the decreasing tendencies when compared with the control group. The litter number in experimental group III, survival rate in experimental group II and III, body weight at birth in experimental group III and IV exhibited significant increase compared with experimental group I. The female pregnancy rate in both experimental group III and IV recovered to 100%, but there were no significant differences when compared with experimental group I. The pups’ sex ratio had a gradually increasing tendency with increase of vitamin E level, but there was no significant difference among experimental group I–IV. The results suggest that TCDD could induce reproductive toxicity in mice, whereas vitamin E alleviated adverse effects on reproductive performance in mice caused by TCDD.

Abstract. In Indonesia, the Javanese Fat Tailed Sheep is a very popular domestic animal for its meat production However selection to increase body weight has never been done by local farmers. As a result the variability of body weight is high, and expected that application of a selection program can improve this trait Two Steps of selection were done in order to improve birth and body weight. In the first selection, the elite group was established by selecting the best 40 females and 3 males from 12500 sheep reared by local farmers based on their mature body weight and tail length. The control group was established by randomly selecting 40 females and 4 males In the second step of selection, the best 50 % females and 5 % males of the progeny of the elite group was selected based on their weaning weight and tail size. The first selection results indicate that there was a positive genetic progress in both birth and weaning weight. Selection had increased 7.17 % and 5.48 % of male and female birth weight respectively and 9.48 % and 9.78 % of male and female weaning weight, respectively. Positive genetic progresses of birth and body weight were also found after the second selection. Birth weights of males and females were 6.75 % and 7.20 % higher than those in the control group. Male and female weaning weights were 5.60 % and 8.19 % higher than those in the control group, however, selection for weaning weight did not affect reproductive traits.

SummaryLong-term undernutritional stress is often a feature of sheep and beef cattle production, but has only become a major feature of dairy cattle husbandry in the United Kingdom in recent winters when food was short and expensive. An experiment was carried out to study the effects of long-term underfeeding during pregnancy and early lactation on some blood constituents, milk yield and composition and body weight of dairy cattle. Two groups of cattle were fed at 60 and 40% of the estimated requirements for maintenance and pregnancy or lactation for 13 weeks before and 13 weeks after calving, and one group was fed at the maintenance level only for the same period. A control group was fed at 100% of estimated requirements for this period. All groups were subsequently fed at the control level for a further 24 weeks.The experiment showed that cows undergoing long-term nutritional deprivation were able to maintain concentrations of blood constituents within narrow limits; the concentrations of such constituents as glucose or non-esterifled fatty acid did not reflect energy deficit or surplus. The animals remained clinically healthy during the underfeeding and recovery periods. The results suggest that debility occurring under field conditions in association with reduced food supply may be due to a multiplicity of factors or to severe imbalance of specific nutrients, rather than to energy or protein deficit alone.There was a difference in efficiency of utilization of energy of 19% between cows in the most severely underfed groups which maintained lactation and those which were not able to maintain lactation. There was evidence that this difference in efficiency was detectable within a few weeks of the start of the period of reduced nutrition. Animals which were less affected in the early stages of food deprivation were also those which maintained the advantage through the deprivation and recovery periods.

Abstract The effect of feed mixture supplementation with MgCl2 on alimentary tract microflora, haematological markers, and selected parameters of reproductive performance of sows was investigated. The animals were divided into control group (K) and two experimental groups (E1 and E2). The sows from the experimental groups were receiving 1 g of MgCl2 6H20/100 kg b.w./day, which constituted 120 mg of pure magnesium, administered in a small portion of a feed mixture. The sows from group E1 were receiving MgCl2 every day for 30 d, whereas sows from group E2 for 60 d. A significant decrease in the count of E. coli, Providencia sp., and Proteus sp. was noted in faeces of the swine of both experimental groups. The study has also demonstrated a reduced number of lymphocytes and an increased number of granulocytes in blood of the sows receiving MgCl2. Feeding of pregnant sows with the addition of magnesium salt decreased the mortality rate of newborn piglets, increased the survival rate of piglets until 21 d of their life, and increased body weight values of litters originating from experimental sows, compared to the litters of control sows.
