“…However, further research needs to be done to clearly establish the amount of milk fed to the kids in order to ascertain the effectiveness of the rearing system in terms of net saleable milk yield. Studies done in cattle show that application of restricted suckling improves milk yield (and, therefore, saleable milk), increases lactation milk yield and maintains the condition of the dam (udder health) than bucket feeding (Boonbrahm et al 2004;Fröberg et al 2007). …”

Production objectives and breeding practices of smallholder households participating in dairy goat breeding projects were analysed in relation to their ability to bring about sustainable genetic improvement in the dairy goat flocks in Kenya. A stratified survey involving 311 goat keepers in 4 project sites was used. This employed both qualitative and quantitative research methods to get a holistic view of dairy goats, and take into account the full array of contributions of dairy goats to the smallholder households. Milk production and sales of breeding stock were high priority functions for the objective to create a financial buffer. The breeding objective traits that farmers perceived as being of primary importance were milk yield, growth rate, body size, fertility and disease tolerance. There were logical trade-offs in the choice of these traits by farmers. Female dairy goats were mainly culled due to old age, poor fertility, small body size and poor health. Farmers did not place a large significance on unsatisfactory milk performance when culling female goats, mainly due to the very small production size and the high demand existing for breeding animals. Factors affecting milk yield and flock size presented satisfied a P<0.1 significance level. The performance levels of dairy goats were mainly influenced by breeding strategies and the resource availability at the farm level. The optimisation of genotype x environment interactions remains the biggest challenge given the objectives set by the farmer.

“…Suckling twice daily as opposed to unrestricted suckling has a lower effect on reproductive performance (EDMUND, 1977). The possible cause of poor reproductive performance among RS cows could also be related to a nutritional effect, as cows which yield more milk would be expected to have less nutrients available for reproduction, as reported by WILTBANK (1970), BUTLER and SMITH (1989), TERQUI et al (1982) and TERVIT et al (1977). However, SHORT et al (1972) andMEJIA et al (1998) showed that suckling increased the postpartum anoestrus interval independently of nutrient intake.…”

Forty Thai x Holstein-Friesian (HF) crossbred dairy cows (75 % and 87.5 % HF upgrade level) with calves were used in experiments to investigate restricted suckling (RS) versus bucket rearing (BR) and hand versus machine milking in Thailand. Calves were kept indoors and remained with their dams during the first 4 days and were then allocated to the RS or BS treatment. Milking was done twice daily and RS-calves were allowed to suckle for 15 minutes after milking. All experimental animals were fed according to requirements with concentrate supplements, minerals and water ad lib. This paper reports effects on reproductive performance and weight of cows. Calving to first oestrus interval in cows with RS and BR calves were 72.2 ± 2.5 and 54.7 ± 2.5 (p < 0.001), respectively, and days open 114.2 ± 6.68 and 86.5 ± 6.7 (p < 0.01). Milking method (hand or machine) had no effect on days to first oestrus and days open. Primiparous cows had a longer calving to first oestrus interval than multiparous cows (p < 0.001) (72.3 ± 2.8 vs 54.5 ± 2.3) and a longer days open period (p < 0.01) (114.4 ± 7.4 vs 86.2 ± 6.1). Body weight change of cows during the first 2 months of lactation was not affected by any treatment or systematic factor tested. Die Rastzeit und die Serviceperiode der Kühe mit partiellem Säugen, respektive ohne Säugen der Kälber, war 72,2 ± 2,5 und 54,7 ± 2,5 (p<0,001), und 114,2 ± 6,68 und 86,5 ± 6,7 (p<0,01). Die Melkmethode (Hand oder Maschine) zeigte keinen Effekt auf die Rastzeit und die Serviceperiode. Erstlaktierende Kühe hatten eine längere Rastzeit (p<0,001) (72,3 ± 2,8 bzw. 54,5 ± 2,3) und eine längere Serviceperiode (p<0,01) (114,4 ± 7,4 bzw. 86,2 ± 6,1) als Kühe in späteren Laktationen. In den ersten 2 Monaten der Laktation verloren die Kühe 4 -5 % ihres Körpergewichtes. Es war kein Einfluss der Behandlungen festzustellen.

This paper reports results of an experiment comparing the effect of hand or machine milking and restricted suckling or bucket rearing of calves on reproduction and cow body weight of crossbred dairy cows.

“…In ewes, McKusick et al (2002a) stated that the cisternal milk fat but not milk protein percentage was lower than in alveolar milk (4.49 % vs. 7.92 %). The suckled cows do not release all of their milk during machine milking, so that the low fat percentage can be partly attributed to the fact that it is only part of the milk stored in the cistern (Boonbrahm et al 2004a). Levy (1964) observed a decrease of about 90 % of fatty acid synthesis in rats by 24h of weaning.…”

“…Early separation of the calf from the cow is the basis of the modern industry, but the cow-calf rearing system is useful in organic and ecological farms where healthy rearing and production is required. There are a number of studies reporting on higher weight gains during the suckling period for restricted suckling calves compared to the artificial rearing system (Fallon & Harte 1980, Boonbrahm et al 2004a, 2004b, Shamay et al 2005, Fröberg et al 2007. Bar-Pelled et al (1997) reported on a better cow and calf health for the nursing system, higher height at the withers, an earlier age at calving and a tendency towards higher milk production during the first lactation.…”

Effects of calf separation and injection of oxytocin on milk performance and milk composition of the Polish Red cows

2013

The aim of this study was to analyse the yield and composition of milk from Polish Red cattle after 12-h isolation of calves. Sixty six Polish Red cows were kept together with calves. Control milkings were carried out once a month after 12-h isolation of calves. Five subsequent milkings after calving were taken under consideration. In the season (May-July 2012) oxytocin (1 ml, 3 min before control milking) was injected. The milk of cows milked mechanically after 12-h isolation of calves was characterized by a very low fat content (0.47-0.58 %) depending on the month after calving. There were no differences in protein and lactose content compared to the standard composition of cow's milk. The milk yield was 6.16 kg in the first milking after calving and 3.55-4.01 kg in the four further milkings. After administration of oxytocin a significant increase of milk was observed in the first (12.9 kg) and subsequent months of lactation (8.5-12.4 kg). Milk fat content was significantly higher (4.14 % in the first and 3.39-3.86 % in the further milkings).
